Just a thought. I noticed that I've followed enough tags that most of the items on the global feed are on my user feed, so I started to wonder what the global feed would look like if it were only comprised of tags and users I don't follow. Surfing through the 'tags' list is nice for finding new tags, but I've found it's more useful to me to follow tags I've seen in context--that is, I find it more useful to go through headlines and find tags than to check through each possibly interesting tag to see what the headlines look like.
I'm curious what you guys think about this--especially kleinbl00, since I'm about 75% sure he'll point out something I missed and make me realize why this was a terrible idea in the first place :P
