I was checking out the British Psychological Society's Research Digest blog series on "the bloggers behind the blogs." The series features Vaughan Bell, the man behind the Mind Hacks blog that I admire, and Jesse Bering, whose Scientific American blog Bering in Mind is always fascinating. I noticed that all of these bloggers report that they now "tweet" as well. Not to be left behind, I decided to sign up, too. So now I'm on Twitter. Athough, like Scott Greenfield at Simple Justice, I worry about de-evolution -- "Orwell's nightmare on steroids." Also, I confess that I don't know what I'm doing.
