I love RSS and subscribe to about 150 sites or so. I do two things that make it a lot easier though. First, I have a "Read" folder/tag for blogs that I _need_ to read. There are probably ~5 blogs in there total. Second, I have a 'Mread' as in "Mark as read" folder for things that I don't need to read at all, but are available for a quick search as they contain useful information. Between these two I hardly feel like I need to read a ton, but I still get great usage out of RSS.
