My friend Rob, just luanched the The Micropreneur Academy. Here is a bit more information on it.
The Micropreneur Academy, an online learning environment for solo software entrepreneurs, is opening its doors to new enrollments soon. Launched in April by noted software blogger and entrepreneur Rob Walling of Software by Rob, the Academy takes developers and entrepreneurs through the process of building and launching a software product (including web applications) with a focus on online marketing topics such as blogging, buzz marketing, social media marketing, and search engine marketing.
Academy members support one another through the private forums and a members-only LinkedIn group and they follow a proven blueprint for finding a profitable niche, building a product, launching, marketing, and supporting it as a one-person software company. Many current members have launched or are launching their own product/web app in the first few months.
Look for a review of the Academy in Bob Walsh's upcoming book, The Web Startup Success Guide.
Gyutae Park from Winning the Web just launched a new membership site called Winners Circle. I don't normally post about stuff like this but I wanted to mention it because I think it has a lot to offer marketers of all levels.

Winners Circle is unique in that it uses real case studies and specific examples to show what works and what doesn't. Gyutae isn't claiming to be a super guru or anything like that but he's good at analyzing successful sites and breaking down step-by-step how they reached the point they're at today. For example, the first case study included shows how a small site beat out huge companies like Toshiba and Wal-Mart in Google for a very competitive keyword. It's very interesting analysis that reveals some little-known link building strategies as well. I recommend you check it out - you can't find this sort of information anywhere else.
Winners Circle features weekly case studies, bi-weekly interviews, and some other bonus material. The program costs $47/month but the first 200 get in for $27/month and the first 50 get a free personal site audit from Gyutae.
Join Winners Circle and give it a try.
