You’ve heard of blogfat; well, I’d like to point out another phenomenon called blogbrain. This affliction is characterized by an inability to focus on other tasks. The blogger may begin to think about life in terms of blog posts ("gee, I should blog about this" or "where's my BlackBerry? Must write this down!") and obsessively check other blogs. When I first started this blog it was sometimes a chore to come up with new topics every few days. Now I have to restrain myself from constant updates. Yup, definitely got blog on the brain. See also blegging, blog hop, and bloggable.
Are you a sufferer?
