Apart from the fact that the 1.0 version seemed a little slow to me, I just found it too time consuming to set up each of my several hundred feeds the way I'd like them. The software expects you to filter by content - but this misses the whole point of blogs. Blogs are unpredictable. A site like boingboing.net will talk about everything under the sun just because it is cool. If I filtered it by content I'd miss half the posts that interest me. True, I could set up individual filters for each of my feeds - but who wants to spend the time doing that? Also, even though you can group folders hierarchically, you can't set preferences for all the feeds in a folder (presumably because they assume the folders don't represent feeds, but are content filters instead). This is a pain, because I like to group my feeds and then set my preferences by group, rather than individually by feed.
