It appears that Stumbleupon.com will be acquired by Ebay and not Google. In response, Google is launching a similar feature in their toolbar that suggests potentially interesting websites based on your browsing history.
Man I would love to see what some other peoples’ browsing history is, wouldn’t you? This would give you keen insight into what their next purchases could be. Speaking of purchases, Google is relaunching Froogle as Google Product Search. No Google will be able to take the known history of your internet activities and match it up with ads and product suggestions.
Google loves to use my browsing history to serve ads against me 🙁
