Google was no doubt hoping it had heard the last of the privacy issues surrounding Buzz, the social networking functionality it introduced to Gmail in February. But thanks to an international group of regulators, that's not quite the case.

When Google rolled out its social networking service, privacy controls were not, shall we say, a priority. In its rush to get into the game dominated by Facebook and Twitter, the search giant freaked out a large number of users by making their list of contacts public and failing to allow them to block people from following them.

Google announced its Buzz social networking search feature on Tuesday, and quickly followed up with a fix designed to quell privacy concerns on Friday. However, not everyone is appeased. 

Buzz is a feature that Google added to Gmail -- and eventually plans to include in Google Apps and potentially other products -- that adds real-time communications and media sharing, a la Facebook and Twitter, to the e-mail program.
