Blog post somewhere that shares the tale? I've had a little side project that I did a few strips for but then never posted because I figured I'd have to be willing to dedicate way more time than it would be worth to build an audience. Sounds like you may have "cracked the nut"?
1. Always update on time, every time. Never miss a beat if at all possible by making comics ahead of time and posting them in advance with a delay.
2. Write & draw what you love, whether it is video games (PA, PVP, etc), sex jokes (leasticoulddo), anime (megatokyo), music & life (questionable content), nerdy awesomeness (xkcd)...you get the idea.
3. Connect with your fans by blogging as much as you post strips. Let them feel a part of the creative process and help them get to know you.
