My buddy Chris Williams has started a new web site/community dedicated to all things VB.NET
Chris is a VB.NET MVP and has been very involved in growing development communities wherever he goes so check out this new community - especially if you're into XNA as well since there are a number of XNA (VB) tutorials on there as well.
EDIT: It might help if I actually include the URL to his site: http://ilovevb.net/
