That, in and of itself is not that interesting - but combine that with Google's inclusion of Froogle into the front page, and things become more interesting. The comparison shopping field, including places like PriceGrabber (Disclaimer: OSDN is an affiliate of PriceGrabber) in the US, Kelkoo/Yahoo! overseas, Froogle, and MSN is heating up in competition. Now that search has been monetized, the next battleground for big money is in comparison shopping, beyond MySimon and other smaller ones.
