I designed this blog system for threesquared.net. You can see it in action on the main page. It allows blog posts from verified users and comments from visitors. The data is stored in a SQL database. The script includes an admin section to edit or remove blogs or comments.

Not a blog so much as a journal -- anyone can edit it who has access to the directory. But it can be used by a person to keep track of their own life and whatnot, or by a group of web developers working on a project. You can rate the events to show how much you liked them, and you can also set how signifigant they are. Simply extract to a directory and you're good to go. Uses valid HTML and CSS.
