How much interest is there in following something like this? I've had some startup ideas I've been mulling around with for years and finally decided to jump in head first. One thought that crossed my mind was writing a blog detailing my progress, obstacles, thoughts, etc throughout the process. I feel like, whether successful or a failure, the process would be interesting and useful to others. Any thoughts on this? Anything you'd like to see specifically covered?
