Today marks the 1 year anniversary since Bing Australia or http://bing.com.au launched. It may not have all the features of it’s US cousin, but Bing in Australia continues to do well locally. Microsoft say more than 3 million people have visited Bing in Australia every month since launch.
The most recent Bing feature to launch was Maps, but were still waiting for Travel and Shopping.
It would have been a nice touch to have a birthday-related background today, maybe for their second ?
