Good database with broken features – ChessBase Online Review

It's great for looking up games and ideas for openings, however the Facebook feature of posting your games seems to be broken after first use... This would be a fantastic app if you could share your games via email or Facebook. Otherwise it's mainly to check up on games. Ability to manage pgn games is also not finished. You can't make notes or rename the pgn files to manage them. Auto naming just clutters the saved games and you can't sort it out after a while.
