Rootly lets you search the news kind of like Google News, but with more customization features. News is divided into about a hundred categories like bonds, horse racing, and web 2.0, and you can pick and choose which ones you want to see on your homepage.
The search is a little slow (possibly too slow for some), but it seems to work well enough. Interestingly, blogs are prominently featured in search results. Other than that, the main draw is that you can filter news on a very granular level.
