BlogSpace looks like an uber-wiki.

From http://www.blogspace.com/about/:

_The key to a Blogspace site, as with most sites, is the content. However, Blogspace sites are slightly different than most. First, Blogspace sites can be easily edited over the Web , through any web browser. (We're also thinking about adding support for WebDAV? and other formats.) Second, Blogspace sites can hold not only text, but also structured and semi-structured forms of data . Third, Blogspace sites use a powerful linking system to let you categorize and manage all of your information in a permanent and useful way._

_But it's not only your content that Blogspace handles. Blogspace allows you to take comments from your readers on any item. And you're not only limited to things on your site -- Blogspace lets you point to things on other web sites too. But, because the web changes so rapidly, Blogspace watches every page you link to to see if it's moved and downloads a copy in case it ever goes off-line. It also makes it really easy to update your site when a page has moved or disappeared._

_We're also working on ways to import your email into Blogspace, so that it too can be linked and categorized with all the power that Blogspace provides. You don't need to worry about security. You get to decide who can view, edit and administer every item in your Blogspace so that you can keep your private information private._
