Steve Yegge just might help g+ steal some market share from facebook yet. Every time he releases something like this on g+ I end up spending a few minutes on the site that I would not have otherwise.
I'm actually seeing a significant amount of longer-format posts (especially from technically-minded people) on Google+. It's a mix of a Facebook status update and a Facebook note and it's pretty easy to write and publish. (Steve's privacy setting slip-up notwithstanding...) In a way Google+ seems to be doing to Tumblr (and in lesser degree Posterous) what Facebook did to Myspace.
