Nice, short profile from the San Jose Mercury News of the Bloglines news aggregator service: Bloglines aims for simplicity. Greg Linden also has a nice summary of why he likes Bloglines just out: Bloglines and feed readers.
There are plenty of other services like Bloglines, of course. We list a number of these here: RSS News Feeds & Blog Search Engines. And if we don't have it, Fagan Finder probably will: Fagan Finder: Weblogs, Journals, & RSS.
