It's hard to compare different populations because of the way ELO works. Maybe if chess.com and those other sites host a common-players tournament to establish some links between their ratings, then it would be more useful to compare.
Rating in Chess.com Vs Other Websites
Please note that Chess.com policy is that we do not discuss or make comparisons with our competitors in our own forums: while it is fine to talk about how ratings on Chess.com may differ to theirs in a general and non-specific sense, we don't need to name them to do that, which is regarded as potential advertising.
I have removed those references from the previous posts.
Thanks,

Hi Guys - I find that the ratings in chess.com are bit more standard than in other websites. Do you guys feel the same..? My rating in chess.com is around 1500 and elsewhere it is around 1750.
