Welcome to your Friday Open Thread. It's that magical time when you get to talk about whatever you damn well please here on Lifehacker (as hosted by her sub-blog Hackerspace). Head on down to the comments to get your chat on. If you plan on sticking around a while, we host open threads every M, W, F right here. Now...you said you were a doctor of what, exactly?
