MyBlogLog has rearranged its profile pages and decided to put a lifestream of the user's activity in the center. It shows your latest blog posts, diggs and similar items, which you can see in the screenshot of my (horribly outdated, I know) profile below.

Now, I've always been a fan of the lifestreaming concept, but in my opinion not one of the many services that do it (Profilactic and little known Correlate.us come to mind as the best ones) have managed to make it exciting enough. Sure, it's nice to see your social networking/blogging/other online activity in one place, but I'd like to be able to organize it, categorize it, act on it, and generally do stuff with it.
