I'd love it if besides showing player's stats on wins and losses chess.com would display a players most popular openings and defences, maybe with w/l/d percents?
I only like the idea if it can be disabled... which I would do. You're basically advertising your weaknesses to your current and future opponents. 
When I start a game with someone I sometimes check out their old games. I'd love it if besides showing player's stats on wins and losses chess.com would display a players most popular openings and defences, maybe with w/l/d percents? I've just seen this on databases and thought it would be super cool on here. You could see how diverse a player is, maybe ask them about openings (if they're successful at them) etc...
Any thoughts? Horrible? Cool?
