I’ve been trying to invite a few friends to Orkut (Google’s own social network) and noticed a very scary issue …

Orkut (Google) gives an error whenever I try to invite people who have yahoo.com email addresses.

Other addresses, like @njit.edu or @aol.com or even @hotmail.com seem to be working.

So, if this is a real technical bug, then it’s a really stupid one. If it’s corporate policy … then, to Google, how is Microsoft ok, but Yahoo not?!
