Thomas Marban's PopUrls has been around for some time.It's a 'quick take on just about every sector on the web', and continues to grow in popularity.
In recent weeks, Thomas has been turning up the volume a bit, with a new separate IT page, numerous new features, more content, and earlier today, an all-new cluster view.
Unlike Guy Kawasaki's recently-introduced Alltop.com, PopUrls doesn't break down categories to pages, but instead, attempts to give you a quick view of the web, updated dynamically, on one page.
Obviously, that's somewhat impossible, but we find ourselves visiting daily. There's something there for literally everyone .... and probably something that you wanted to know about and didn't.
