The US version of MyBuzz went live a few weeks ago and it's already filling up nicely with American and Canadian content. Although both sets are in English, we've separated the US from the UK/ Australian so that we don't get confused by questions about quarterbacks and presidents.
In a fine piece of timing IGN US posted their review, giving us an 8.9 and an Editors' Choice award. They particularly liked some of the features we've released in patches post-release. Who knows, perhaps some of the other things they're wishing for might become available in future patches too...
