Yeah, as much as I agree that it's important to be aware of the negative effects of having so much information readily accessible, I also think it's important not to forget the positive ones. Sure, it's bad when I find myself checking myself checking my RSS feeds every five minutes instead of working, but when I think about all the interesting, entertaining, and truly useful things I know now that I didn't know about a year ago, I realize I learned a lot of them from reading my RSS feeds.
