RSS is a way to consume a LOT of information very quickly, and STORE it in nice categories if you miss it. So I can catch up with a small blog's output at the end of the week and, if I so choose, read EVERY article easily in one sitting. You think on Friday I'm gonna go browse that same site's Twitter feed on their page (digging through all the messy @ replies) and see what they did that week?! Or go to their Facebook page that is littered with contests? No way dude, I'm too busy for that!
Apart from email lists, RSS is the best way you can collect stuff across the internet to read quickly, and I am so irritated when that choice is taken from me.
