Blogging and sharing company Posterous has announced via its company blog that it has been snagged by Twitter in an apparent ‘acqui-hire’, with Twitter interested mostly in the people, not the product. Various Posterous engineers, product managers and more will join the Twitter team and the existing ‘Spaces’ that users have will remain up and running for now.

This is all despite Posterous being emphatic just 19 days ago that it had ‘no plans to sell’.

Twitter says that it will give users ‘ample notice’ if it is going to make any changes to the service. We’ll take them at their word on this one, but if I was someone running a personal blog on Posterous, I would think about finding another place to host it soon.

In its own announcement, Twitter says that its acquisitions of ‘people and technology’ have enabled it to make the service better. We’d read this to mean that you’re likely going to see the service being shut off after a grace period of some sort. Twitter even states that if users would like to back up their content or move it, that they will share ‘clear instructions’ on how to do so within the coming weeks.
