Posterous is a web publishing service that allows users to publish via email. Sounds pretty simple and it is. Basically you send text and attachments (video, photos, audio files, etc.) via email to an address at Posterous and then Posterous will publish that information in blog format. You can also go a bit deeper and use Posterous to publish to not only your Posterous web site, but also to other sites such as Facebook, Twitter, Tumbler and even your own weblog. This is a very easy way for a teacher to establish a web presence. For example I could see a teacher using this to post homework assignments and classroom news. For those teachers and administrators who are looking for an easy way to get started with web publishing Posterous just might be the tool they are looking for.
