Introducing Posterous Spaces from Posterous on Vimeo.
The other cool thing about this update is that the Spaces feature is also included in the Posterous Android and iPhone mobile apps so that you can make sure that your content is organized and flowing to the right group of people every time. They've also added a couple new features including a new reading experience, 3x faster load times, and five new professional looking themes. If you are a new blogger, or an experienced blogger who likes things simple, accessible and easy-to-use, Posterous is a great solution for you.
