Yes. I think its good to see how better players deal with mistakes by their opponents. And its easier than reading a book trying to work out the positions in your head.
I have a quick look games by those who challange me to see what they like to play. Other than that i dont look at games here unless someone posts a game in the forums. I look at master games 'live' on a different website.
Look at other people's games even though you're not playing them? Sad as it is, I do this quite often!
