I'll go on the record and say that about.com is the worst website in the history of the world.  It was recently talked about favorably in some tech press because it started using WordPress.  But I still hate the site.  It's so full of useless ads and unrelated links that it takes hours for a single page to load.  But the site has such an unbelievably large amount of information that it always come up in search results.  Whenever I see it as one of the results, I automatically move on because I know I'll find nothing useful. 

Boycott about.com.  It's stupid and slow.
