Tech crunch has a little article about Memorandum and Blogniscient. I have tried them both, I didn’t actually think they were that great.I can tell you why I definatly won’t be using them. I can’t flipping spell their names when I type them out in a web browser!
Blogniscient is a blog news organizer that, like Memeorandum, uses a propreitary algorithm for determining what’s hot in the blogosphere at any given time. Unlike Digg, which creates news items based on user bookmarking and subsequent voting to determine front page items, Blogniscient and Memeorandum are automated.
