MemeStreams is yet anothe blog hosting server. It may not be as feature rich as Blogspot. But what I liked most there is their categorization, as well as the ability to see the posts in a specific category from all the members there. Here you are how they define themselves.

MemeStreams is a social web surfing tool that helps communities of people work together to find interesting content on the Internet. It allows you to maintain collections of recommendations for Internet content, and it employs state of the art content rating technology to sort through your friends' and colleagues' recommendations in search of information that matters to you.

As you may have noticed, they have a social network as well. Finally it is really interesting that people like Michael Lynn (Abaddon) and Billy Hoffman (Acidus) are having their blogs hosted there.
