Wonder if it'll be able to compare to Tumblr from a social media-quality perspective now that it's private like Tumblr has been.

I just paid Tumblr $25 last week to have 7000 people see a funny joke I made last year. Win-win. The users get a sensible chuckle, and Tumblr gets a little walking around money. Can't believe Tumblr Blaze is advertising done right.
