Posterous is a simple blogging platform started in May, 2009 funded by Y Combinator. 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. Posting can be done by logging in to the website's rich text editor, 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). Many social media pundits consider Posterous to be the leading free application for lifestreaming. The platform received wide attention when leading social media expert Steve Rubel declared he was moving his blogging activity entirely to Posterous.
Posterous also has its own URL shortening service, which as of March 2010 can post to Twitter.
Posterous allows users to point the DNS listing for a domain name or subdomain they already own to their Posterous account, allowing them to have a site hosted by Posterous that uses their own domain name.
