Something that would probably be worthy of a blog post: the Google results in the Bing It On challenge are unfairly neutered.

Try doing the Bing It On search for something like "radiohead". You see two columns of plain old search results, both are fine. But if you go straight to Google.com and search for "radiohead", you get more than just the normal search results, you get a bunch of extra details on the right side of the page. Those extra details are super relevant and helpful, like the band's members, popular songs, upcoming events, etc. If you go to Bing.com and try the same thing, it also has some extra stuff on the right, but it isn't nearly as good.

This happens for lots of searches. Google often shows some really helpful domain-specific information, but that extra stuff doesn't show up in the Bing it On challenge.
