I'm in sympathy with TexRat here. A lot of commercial application developers have grown up in the MS world as that is what the corporate world tends to be using a lot of the time.

Whilst the Wiki has a lot of information I think we could get a LOT more devs onboard if we had a walk through in a sample application from start to finish. Bring in elements and references to the design guidelines etceteras along the way to form a way of working. If we can find something simple enough as an application but covering a few basic areas I suspect we are onto a winner. Maybe even go with a series of simple applications?
Charles Petzold, whilst in the Windows camp, did some good examples for the Windows world, surely we can for Maemo too?
