The latest buzz in the IT markets is that of StumbleUpon to introduce a new fourth version of its toolbar on the 1st of September. The new toolbar will be more simple, searchable and more social and will also have dozens of new product features.

The site is growing constantly and consistently with nearly 10 million stumbles recorded recently and 8 million registered users. The company has been progressing in leaps and bounds and is also about to open up a sales office in New York.

"Stumbleupon isn't random. It learns what you like based on your rating of the sites you see and topics you pick and gears suggestions towards your preferences."
