It reminds me of my first five years of blogging at rexblog.com when no one read it and I was completely random in what I posted about.
I haven’t figured out how to add comments to it (please don’t tell me how) so there’s no pretense of community. (That sounded down-right unfriendly, I’m sure, but there are plenty of other places where I commune.)
I’m still at that place where I don’t think “I’m writing” when I add stuff to it.
So few people use Tumblr that it hasn’t been invaded by the tech-punditry that will ruin it by demanding more features and a business model.
It hasn’t been infested with people who make posts in numeric fashion.
