One thing I really hate is when you get behind on something and get caught in a vicious cycle. Say, like, reading a certain person's very very frequently updated LiveJournal. Like, they do an event where they post every half an hour for an entire 24 hour period. And you kinda don't feel like wading through it (er, not very good choice of words), but you don't feel like you should skip it entirely, and so you put it off until later when you do feel like it. Except the next candidate later time, there's now a whole bunch more posts just from the regular daily posts. And so you put it off again.
With a vicious cycle, at some point you just got to give in and say, screw it, I'll just give up on "catching up" and start from scratch now.
But I ended up reading all of August anyway. And now it's 4am, oops.
