Blizzard have launched a new official community site
for Diablo 3:
Welcome to your sanctuary for all the latest developments from New Tristram and beyond, featuring community forums and regular blog updates. You can post comments and share Diablo III news items via Twitter, Facebook, and other popular social media outlets, and be sure to check out the new Diablo III news feed regularly. We’ll use it to share the latest Diablo III information and to highlight recent community activity, including your most entertaining videos, art, comics, fansites, and more.
The first one is called "Challenge of the Diableards
" and challenges you to outdo other Diablo fans in a battle of the beard.
Note that one of the URLs floating around for this site is http://battle.net/d3/, but if you're in Australia it attempts to redirect you to the SEA Battle.net network, which doesn't look like it has this new site set up properly. Make sure you access it using the US Battle.net URL, http://us.battle.net/d3/en/
