Posterous is a simple microblogging platform started in May, 2009. It boasts integrated and automatic posting to other social media tools such as Flickr, Twitter, and Facebook, a built-in Google Analytics package, and custom themes.
Updating to Posterous is similar to other blogging platforms, but it is particularly designed for mobile blogging. Mobile methods include sending an email, with attachments of photos, MP3s, documents, and video (both links and files).
