The blogging platform, Posterous, is undergoing a major makeover, renaming itself Posterous Spaces, which takes a social networking approach to sharing private and public user content. Members of the site will still be able to share photos, videos, and written content as before, but in the new platform they can configure “spaces” (groups and types of followers) for the type of content they want to share.

Posterous Spaces are like mini blogs which you set up for different types of followers. You might have a private Space for your family, and another one for your friends or members of your club. You can set up as many Spaces you like, each using a different template or custom theme.

Creating a Posterous Space is very much similar to starting a new blog. After adding a name for your Space you can invite your existing Posterous followers, contacts from your address book, or by direct email to view your private or public Space. As you might expect, you can also share the content of your Spaces with several other popular online services, including Facebook, Twitter, and YouTube. Each of your Spaces gets its own unique URL.

In an interview with Mashable, Posterous founder and CEO, Sachin Agarwal, said “people really love using Posterous because they can control how they share and who sees what they share“.

The Posterous iPhone app will also incorporate the new focus and design for Spaces.
