We launched SqlJunkies.com this week (on Sunday during PDC). So far the response has been great.
Shannon Horn recently wrote an article that we posted accross bot SqlJunkies and DotNetJunkies. You can read it and discuss it in the forums.
On DotNetJunkies there is an interesting conversation where some users are modifying the code and converting it to VB.NET.
On SqlJunkies there is a conversation going on about the performance of temp tables versus the use of table variables.
There are some bugs on SqlJunkies.com that we are working out, but its coming along nicely. We'll be posting new builds weekly as we fix bugs and add features. This weekend we will be migrating DotNetJunkies.com to use the new code base that we built for SqlJunkies.com (we call it the Atomic Community Engine - ACE). In a few months we'll be releasing the source code.
