In news that must have surprised no-one, Posterous has announced that it will be turning off the lights in a few months.

On April 30th, we will turn off posterous.com and our mobile apps in order to focus 100% of our efforts on Twitter. This means that as of April 30, Posterous Spaces will no longer be available either to view or to edit.

Now two of the original co-founders of Posterous — Garry Tan and Brett Gibson — are soon going to launch a new blogging platform called Posthaven that pledges never to be acquired and to be a home for your blog that will last forever.

We’re not going to show ads. We’re not looking for investors. We’re going to make money the best way we know how: charging for it.

Charging $5 per month to be exact.

It promises to be up and running by the end of the month, but at the moment it’s just an extended pitch for the product. As a manifesto of values and a statement of intent though, it gets certainly gets my vote.

If you’re wondering why you should want to place your trust in some of the people behind Posterous again, it’s worth knowing that Garry Tan left the company before Sachin Agarwal ‏sold it to Twitter:

I don’t want to dig up the past, but the truth of the matter was I didn’t agree with my cofounder on the direction of Posterous, but I also wanted to support him in his pursuit of the direction he believed in. It was one of the most painful experiences to have to walk away from my baby.

I’m pretty well settled on WordPress.com now (having abandoned Posterous in 2011), but I’ll certainly be keeping an eye on Posthaven in case I ever feel like a fresh start.
