Most people I know hate Orkut these days. Yahoo! has blown Google away with its 360! product. But does Google hate its own Orkut also? According to a Search Engine Roundtable Forum thread named Have Google Banned Orkut? it seems as if Google has delisted Orkut from its index. Try a simply search on orkut or even on www.orkut.com or a site command query all results show nothing for orkut.com. It is not a simple case of the robots.txt file disallowing. Yahoo! has indexed a whopping 25,788 pages of the site and has ranked it number one for its name at at yahoo search, so it makes you wonder.
