Every site will have its strengths and weaknesses. Personally, I don't ever run into any serious issues with Chess.com.
This site is so buggy

This is a lot worse than most sites. Why is it that whenever I start a game, I get a pop up telling me my connection isn't strong enough, but then when I press <play> again, the site immediately starts searching for an opponent?

because your connection wasn't good, that's why
That's nonsense. My connection was fine.

That’s because some of the people who posted those posts either were muted or deleted the posts.

Individual posts don't get moved (topics are another story). The options are the posts were deleted by the poster, the posts were deleted by staff/moderators, the member was muted, or the member's account was closed for abuse.

Or that you have bugs on your site which you seem to be completely ignoring.

Yes, google chrome is amazing for any website that includes multiplayer things. Safari isn’t amazing for those.

Do you work for chess.com?

The *block* button doesn't work. Or rather, it doesn't give you any feedback when you press it. It may or may not actually block people.

No he doesn’t xD
Does anyone else find this? It's broken in so many ways. I wonder if [another site -- VP] is as poor?
