I feel the same way about YouTube. I spent like an hour on the site last night watching Wonder Showzen clips.
all these posts and none like this yet. www.answers.com is better than wikipedia. For one, it's faster. But it also brings up references from multiple sites (the first or second of which is wikipedia). So you get your wikipedia info faster...plus you get dictionary.com and other info on your subject. Additionally, it'll bring up google's results at the bottom. It's great...and the plugin/toolbar thing they have is solid
But you do you get unexpected and hilarious surprises like what I recently saw on the Terrell Davis entry at the end of the article, as a stand-alone sentence: "Terrell Davis once popped 30 boners for charity."
