Posterous: CMS for simple web publishing via email

"Posterous is the easy way to get content online using e-mail. You can e-mail content of just about any type (such as rich text, photos, music, video, Word/Powerpoint/Excel/PDF documents, and zip archives) to us. We will post it online in the most web-friendly format, then reply with a public URL that can be forwarded or shared with friends. Account creation is never required, but if a user does create an account, posts from your various e-mail addresses (work, home, and mobile phone) can all be integrated into one blog."

Categories and Tags on Document Sharing Websites

"I usually hate being forced to choose a category from a drop down menu. It smacks of technocracy where the system designer is unnecessarily imposing, subtly or not, a narrow view of how data should be described. This clumsily reasserts the unequal relationship between the developer and user. Instead of being empowered to input your own stuff and personalise your profile, a poor uploading experience can leave you feeling like a patronised data entry clerk. I'm also convinced that it's not the cleverest way to organise content
...
Categories are only descriptions, they are not empty containers compelling somebody to fill them. If there isn't a perfect category available, which is nearly all of the time, you just have to choose the nearest. It's annoying, but common experience."
