WordPress.com reminds you, you can switch from Posterous to their platform!
Twitter has just announced that they are acquiring blogging platform Posterous.

Twitter has confirmed that Posterous would continue to work as usual. But they have given enough hints that things could change in the future.
If you are running a blog on Posterous, you might want to switch platforms to ensure that you can focus on your blog and not the engine powering it.
Automattic developers have posted a blog post on how you can migrate from Posterous to WordPress.com with your blog.
WordPress.com has perhaps the most solid importers available on the web today for blogging platforms and it shows!
