Most of you have probably noticed the "Recommended Diaries" section over there. I'm not sure exactly how it works, but it seems pretty self-explanatory. If you want to see a diary stick around, vote for it. This will help keep some of the discussion alive in the more interesting diaries, instead of having those diaries pushed to another page because of the hourly Lincecum update. Not that there's anything inherently wrong with the hourly update, but you know what I mean.
Vote early, and vote often.
