I am a big fan of the CBS leagues. I like their stat reporting better, the layout of their pages (especially since they are customizable), their live scoring and GameCenter much, much better than the other websites. I have tried over the last four years Fleaflicker, ESPN, EA sports, yahoo (both free and the upgraded version), and MFL and none of them have the attention to UI the way CBS does.
I think MFL is really clunky and they need someone who specializes in UI workflow to seriously snap them into the right mindframe. Same goes for EA Sports and ESPN who clearly cannot be bothered with checking for browser compatibility. Yahoo has a lot of pluses however I really can't stand their reporting at all (I really don't care what the pre-season rankings of positions were, friggin sort by the fantasy points already!).
Can you tell what I do for a living?
