Eric Sink, who has written a lot of different articles about starting a small software business, recently wrote one that hit home for me here at Gaucho Software. The article talks about what he learned after a month of starting his own Micro-ISV, or single-developer software company. His situation is a bit different than mine here, simply because he still has his normal paying job and is programming his Winnable Solitaire on the side, but he still makes a lot of good points in the article.
Speaking of Gaucho Software, I recently configured some discussion forums for the company. I believe it will help me keep in touch with my user population, and will help users keep in touch with other users. There are already a couple of discussions up about XRG, so if you are interested check it out.
