I use my Tumblr blog (or Tumblog, I guess) as a repository for random brain-farts and a dumping ground for the occasional photograph I take in my travels; it also contains some snippets of conversation that I find amusing. In other words, it’s an “everything else” blog.
I suppose you could argue that I could just post all that stuff here, and I’d be hard pressed to come up with a convincing argument to the contrary. Suffice it to say that I enjoy a certain compartmentalization of my inanity.
