Idk, what are your thoughts on these :D

Should chess.com remove RD and be the first website to use rating floors?

Should fide online arena titled players and internet correspondence and uscf correspondence titled players be able to add their title on here/be counted as a titled players?

Should chess.com add giveaway, chaturaji, spell chess, atomic, bughouse, crazyhouse, 3-check, king of the hill and racing kings daily games?

Should arenas be paired by points earned a player or by rating?

What rating is the most accurate in terms of elo, is any one or is an average of all of a players' ratings on sites/otb the most accurate?

What do you mean by the first one, "RD"

rapid rating is the most accurate because blitz and bullet are all over the place

The site uses the Glicko rating system that includes a measure of rating uncertainty called the rating deviation (RD) value.

Thank you.

I'd rather they invested more resources in improving their code base and tech stack instead of chasing flashy new features.

"Should chess.com remove RD" ++ No. A variable RD is the improvement of Glicko over Elo, which uses a fixed RD. Glicko converges faster, but requires more calculation than elo.

"be the first website to use rating floors?" ++ No, that would skew the system.

"Should fide online arena titled players and internet correspondence and uscf correspondence titled players be able to add their title on here/be counted as a titled players?"
++ No. I would even get rid of the "NM" which not all countries have and which differs per country and keep only GM, IM, FM, CM, WGM, WIM, WFM, WCM

"Should chess.com add giveaway, chaturaji, spell chess, atomic, bughouse, crazyhouse, 3-check, king of the hill and racing kings daily games?" ++ No. Regular chess and 9LX is enough.

"Should arenas be paired by points earned a player or by rating?"
++ By points earned, but initially seeded by rating.

"What rating is the most accurate in terms of elo, is any one or is an average of all of a players' ratings on sites/otb the most accurate?"

++ Classical, rapid, blitz, bullet are different games requiring different skills, so it is not a matter of accuracy. You cannot say a rating in tennis is more or less accurate than a rating in ping pong.

Ratings on different sites and FIDE over the board for the same time control differ by a constant offset.
The odds of player A beating player B should be the same by all the ratings.
Hence the rating differences should be the same.
Probability (A beats B per rating system 1) = Probability (A beats B per rating system 2)
Rating of A in system 1 - Rating of B in system 1
= Rating of A in system 2 - Rating of B in system 2
Rating of A in system 1 - Rating of A in system 2
= Rating of B in system 1 - Rating of B in system 2
