A few interesting posts I've found on authors self-publishing...

The first interesting tidbit is Visual Studio .NET Tips and Tricks which has been written by Minh T. Nguyen and is being self-published through the LuLu.com service. Seems like the book has just been released but i am curious to see how well it will fare.

Another interesting tidbit is about Gryphonwood Press who has used POD to publish their low distribution newsletter (or magazine i should say).

Seems like POD (Print-On-Demand) is gaining more attention and is gaining several viable markets!!!
