Guy Kawasaki (website and blog) formally announced Alltop in March 2008. Alltop is a "news aggregation site"...that is, it provides links to top stories for a number of popular topics. The main page contains the topic links (about 150...there were 40 when it started) and each link contains specific links for each topic organized by source.

So if you're looking for up-to-date information that isn't pushed to your system (ala RSS feeds) but is there when you need it, visit Alltop today. Set a timer or you'll be there for awhile ;-).
