I set up a Posterous account last week just to compare it to the ins and outs of Tumblr.
It wasn’t as intuitive or sleek as Tumblr, certainly not something I’d want to revisit every day. It really felt like an inferior blogging product.
While it doesn’t make sense to blog on Posterous it makes complete sense for Twitter to buy it out.
Posterous owns the knowledge on spacial microblogging design, something Twitter wants to get into to keep more people viewing its profile pages for content.
Twitter is more aggressively pursuing long-form content for consumption within its site. It’s moving beyond text because it wants to make its posts more sticky. Twitter wants you to watch a video on its stream instead of kicking you out to YouTube.
I don’t see the Posterous acquisition as a threat to Tumblr. It was a strategic move by Twitter to bring in talent to make the ultimate multimedia canvass which could turn real-time events into an even better and interactive viewer experience.
