If you can send an email, you can blog...

Posterous might be the simplest blogging platform. All you have to do is to send an email to post@posterous.com and  you’re done. The subject line of the email is the post title, the text area is the content. Send a photo and it will be resized and posted. Send a video and it will be converted for viewing on the web. Documents get embedded. For example view my Posterous blog. Posterous automatically send your post to any number of popular sites like Twitter, Facebook, or Flickr. You can also post from your mobile device.
