I have about 6-8 sites that I always need to be fully caught up on. I'll check them a few times a day, and while I don't need to read every article, I need to at least look at the headline of every article up to the last one where I left off so I know I'm caught up. I'm working on a solution to this problem (skim.me, but I don't want it to distract from the question), but we're not sure how many other people browse this way. Are you concerned with catching up on specific sources, or would you'd rather just have content recommended to you and don't care if you missed any updates from any one specific source, so long as you see stuff that's interesting? Do you browse to catch up, or for entertainment?
