Response to Comment From Rafer
Thanks to Scott Rafer for the comment! I'm experimenting with providing topic search results rather than keyword searches to offer broader perspectives on a topic. RSS feeds are there because I like staying up-to-date, sort of like a personalized PubSub. I'm open to change though, so I'll experiment with adding color-coded boxes at the bottom of each post linking to Technorati tags, Feedster, and MSN Search results, all related to the post's topic to avoid tag spam.
