Windows Mobile MSDN Forums & a Kids Programming Language
Just a reminder in case you weren't aware, but MSDN hosts its own forums which include a healthy dose of Pocket PC and Smartphone discussion. If you're looking for an answer to a programming question, it's a great resource.
Amd while I have my blog editor running, I was just sent a link to Kid's Programming Language, which although not currently running on Windows Mobile, still looks very cool. If you have a would-be nerd in your house, you might be able to tempt them away from Instant Messenger and their MP3 player for a few moments with the promise of writing their own version of Grand Theft Auto (although hopefully one that doesn't need an adult rating).
