Okay, so a lot of the RBY move analyses have factually incorrect wording because they're copy-pasted from future gens. Megapost, go!
Note that while some of these changes are massive, they are undisputed; any experienced RBYer will agree with my revisions.
http://www.smogon.com/rb/moves/acid_armor
http://www.smogon.com/rb/moves/barrier
These two analyses state that Reflect is better because it has a higher cap. This is 100% false. No Pokemon will hit the Barrier or Acid Armor cap in a single use, so their stackability makes them strictly better than Reflect. The relevant clauses in the main analyses should be deleted; the note under "Related Moves" for Reflect should be changed to "Reflect also doubles the Defense stat, but does not stack with itself." on both pages.
http://www.smogon.com/rb/moves/body_slam
http://www.smogon.com/rb/moves/slash
The statement in these analyses that Slash is less powerful than Body Slam and Double-Edge is extremely misleading. Slash's crit rate is not just "high", it is 99.6% on most of its users; as such, it is on average MORE powerful than Body Slam for every single fully-evolved Pokemon that receives the move, and more powerful than Double-Edge for all except Parasect.
I would suggest the following rewording of the relevant "Related Moves" text of the Body Slam analysis:
"Slash is an alternative with a high critical hit rate but poor distribution."
And the following rewording of the Slash article itself:
"Competitive Use
Slash is indisputably the best of the Normal-type attacks; despite its low Base Power of 70, the move will always result in a critical hit for any user with a Speed base stat of 64 or more. Unfortunately, the move has extremely poor distribution, with only Persian and Farfetch'd receiving STAB on it; STAB Slash is the main reason Persian is in fact OU. Note that thanks to RBY's critical hit mechanics, this move will ignore any Attack boosts of the user as well as Defense boosts or Reflect affecting the target, so it should not be used alongside Swords Dance; it should also not be used on Parasect thanks to Parasect's low base Speed.
Related Moves
Body Slam is a much weaker alternative with a 30% chance of paralysis and better distribution.
Double-Edge is a weaker alternative with recoil and better distribution."
http://www.smogon.com/rb/moves/bubblebeam
While Surf is indeed strictly superior to BubbleBeam, there are several Pokemon that commonly use BubbleBeam because they don't learn Surf or Blizzard and need to cover Golem and Rhydon. I would suggest the following revision:
"Competitive Use
BubbleBeam is typically not useful competitively, as Surf and Blizzard are far more powerful. However, there are some Pokemon (notably Persian) that learn BubbleBeam but not Surf or Blizzard; for these Pokemon, BubbleBeam is a great move to dispose of Golem and Rhydon."
The words "and reliable" should also be deleted from Surf's entry under "Related Moves".
http://www.smogon.com/rb/moves/counter
There's a typo here in the Competitive Use section; "it's a attack that makes the user goes last" should be corrected to "it's an attack that makes the user go last". There's no problem with the substance of the analysis, though.
http://www.smogon.com/rb/moves/crabhammer
The text in the Competitive Use paragraph correctly notes that Crabhammer is typically more powerful than Surf. However, the Related Moves notes do not, and also don't mention Hydro Pump. I suggest the following revision:
"Related Moves
Surf is a far less powerful alternative with perfect accuracy and better distribution.
Hydro Pump is a less powerful alternative with lower accuracy but better distribution."
http://www.smogon.com/rb/moves/defense_curl
The Competitive Use section says that Defense Curl is outclassed by Barrier. While this is technically true, it is also irrelevant; there are no Pokemon that learn both moves. There is precedent for its niche use on Chansey, as mentioned in Chansey's own analysis, so "literally no situation in which you could ever use this move" is wrong - the Related Moves section also has some errors. I propose the following revision:
"Competitive Use
Defense Curl is hardly ever used thanks to its weak effect and poor distribution. The only place you will ever see this move used is on Chansey, which will occasionally use Defense Curl instead of Reflect for its stackable Defense boosts and higher PP.
Related Moves
Barrier is a Psychic-type equivalent that raises Defense 2 stages.
Acid Armor is a Poison-type equivalent that raises Defense 2 stages.
Withdraw is a Water-type equivalent.
Reflect doubles Defense in a single turn, but does not stack with itself."
http://www.smogon.com/rb/moves/double_kick
Double Kick is a recommended move on Jolteon's analysis, directly contradicting "This move is too weak to be used at all". The Bonemerang mention isn't very relevant either. I recommend removing the mention of Bonemerang and revising the Competitive Use section to the following:
"Despite this move's low Base Power, it is commonly used by Jolteon to deal super-effective damage to Chansey, Golem, and Rhydon. All other Pokemon that receive Double Kick have more powerful options to hit these targets and should thus never use this move."
http://www.smogon.com/rb/moves/double-edge
The link to Body Slam in this article is incorrect; it currently links to the B/W version of the move instead of the R/B version. Moreover, the whole article misses the point of why Double-Edge isn't used in RBY OU; it's not just that Body Slam has paralysis, it's also that Double-Edge is not much more powerful than Body Slam (unlike in future generations where it has a Base Power of 120), and that if you "need the raw power", Hyper Beam is available. I suggest the following revision:
"Competitive Use
While Double-Edge is one of the more powerful Normal-type moves, it is typically shunned in favour of the slightly weaker Body Slam, which has no recoil and a 30% paralysis chance. If you need the raw power, Hyper Beam is typically a better choice with its much higher Base Power. Double-Edge does see use on a few Pokemon that need an every-turn physical attack but don't have any better options; Exeggutor and Articuno are the most common users in OU.
Related Moves
Body Slam is a slightly weaker alternative with no recoil and a 30% chance of paralysis.
Hyper Beam is a much more powerful alternative with no recoil, but has lower accuracy and must recharge if it does not KO the target.
Slash is a more powerful alternative with no recoil, but has poor distribution."
http://www.smogon.com/rb/moves/drill_peck
The analysis is clearly written by somebody who isn't experienced with RBY; Zapdos deals far more damage to Snorlax with Thunderbolt than it does with Drill Peck because Snorlax doesn't have a massive Special Defense stat yet. Mentions of Primeape in UU are also ludicrous, and it should also mention Drill Peck's significant advantage over Normal-type moves of hitting Gengar. I propose the following revision to the Competitive Use section:
"The best Flying-type move available in RBY, Drill Peck is an automatic entry for all Pokemon that receive the move. Unlike the more widely-distributed Normal-type moves, Drill Peck hits Exeggutor for super-effective damage and is capable of damaging Gengar. Zapdos is the only user in OU, making great use of the move to potentially 2HKO Exeggutor and Alakazam, and to 3HKO Chansey, as well as 2HKOing the rare Victreebel."
http://www.smogon.com/rb/moves/egg_bomb
Mentions of Blissey or contact moves (or of Chansey not attacking) in RBY are obviously silly, Double-Edge has exactly the same Base Power in RBY, Body Slam is less powerful, and it does have a fringe use for Exeggutor, allowing it to hit Chansey (recoil off 703 HP makes Double-Edge a poor choice). I suggest the following revision:
"Competitive Use
Egg Bomb's extremely poor distribution and poor accuracy mean that this move is hardly ever seen. It's occasionally used on Exeggutor, in order to hit Chansey on the physical side without Double-Edge's high recoil, but that's all.
Related Moves
Double-Edge is a perfectly accurate option with recoil.
Body Slam is a slightly less powerful alternative with perfect accuracy and a chance to paralyse opponents."
http://www.smogon.com/rb/moves/explosion
Again, mentions of Snorlax in the same breath as Chansey are silly. Also, Gengar is a common user (more common than Golem in the current stats of both Showdown and PO) and should be mentioned. Change "An excellent last resort move and a good way to deal with Amnesia users." to "An excellent last resort move and a good way to deal with Amnesia users or Chansey.", change "The best users of this move are Exeggutor and Golem." to "The most common users of this move in OU are Exeggutor, Gengar and Golem.", and delete "It's a way to deal with Chansey, but keep in mind that you will need to weaken Snorlax to KO it with this move, as it has a decent Defense stat."
http://www.smogon.com/rb/moves/fire_blast
The analysis of this move is correct as far as it goes, but it misses three big reasons why Fire Blast is not used; 1) Starmie and Alakazam love being burned (as it prevents them from being paralysed, slept or frozen) and will happily switch into this move; 2) Every Pokemon in RBY OU that is weak to Fire Blast is also weak to the more accurate Blizzard, with the exception of the uncommon Jynx - and Blizzard hits many other Pokemon as well; 3) Fire Blast can undo freezes. I suggest the following revision to the Competitive Use section:
"Competitive Use
Fire Blast is a powerful and fairly accurate attack, but it is a poor choice in the RBY OU metagame for several reasons. Firstly, the Fire-types that receive STAB on this move are not generally viable in OU. Secondly, it's generally outclassed by Blizzard as a coverage move, as Bug-types are not found in OU and Jynx is both somewhat uncommon and frail. Thirdly, this move's high 30% burn rate often backfires; Starmie and Alakazam are common in OU, and both become significantly more dangerous when burned as it makes them immune to other statuses. Fourthly, this move can thaw frozen Pokemon; freezes are otherwise permanent in RBY and thus thaws are very much unwanted. Because of these many flaws, Fire Blast is almost never seen in OU play."
I'll post later with more corrections; that's just A through F, but my time is not infinite.
