When people write comments, I smile.
I thought maybe I should made some mechanism for putting titles on my blog entries, but then I realised that'd be a lot like subject lines on emails, and those always annoyed me, because I often didn't want to take a stance on what my post was about. So I'd just write really silly ones or really boring ones, usually. Here, I can make a title with bold really easily, and also leave it out even more easily. So I'm happy.
