It might be a mathematician's obsessive-compulsive tendencies, or lack of proper motivation to do other things, but I like to try to keep up with all my rss/atom feeds, and largely with my twitter stream. I tried, for a while, setting up Google Reader with a folder that I didn't keep up-to-date with, and would just check randomly when I was bored, but it never quite sat right with me. I'll star items to read later, but once I get over 20 or 30, and certainly by about 40 starred items, I start getting pretty antsy. Furthermore, I check Reader's 'Discover' link every few days, because the thought of it not being an empty list of recommended feeds is a little annoying. Sometimes I wish I could turn off the recommendation engine, though I suppose not clicking 'Discover' is about the same.
This past week I moved into a new apartment, which was, itself, newly renovated with all brand new appliances. I mention this because one of my new appliances gives me something else to keep up with. My fridge has a pretty productive little ice-maker. As it is summer time, and I'm trying to do a fair bit of running, I need to be drinking lots of water anyway. And I don't like drinking water without lots of ice. So it's nice that there's always ice. At the same time, it's just one more thing to keep up with :)
