For those who want just a small taste of what prominent bloggers are saying, DayPop is a good place to go. It culls its search results from fewer than 60,000 blogs chosen by editors. That means it’s likely to offer up relatively few links to well-known bloggers like Andrew Sullivan and Dan Gillmor. Sites like Technorati, Feedster, IceRocket and BlogPulse scour far more blogs — between 15 million and 20 million each — so searches on those sites deliver far more results, often from obscure sources. While Technorati and BlogPulse focus exclusively on blogs, other sites — Feedster and IceRocket included — offer the option to bring in mainstream news sources.
