1)I have been working on several things for a few years. Last summer, I began posting here because I concluded I need to learn a programming language and write a simulation/game as an educational tool for my health site. For better or for worse, the ideas on the site grow out of my own first-hand experience with getting well against impossible odds. Between continuing to work on resolving my health issues and working as much overtime as I can at my job, I haven't made much headway towards my goals for this site, and even less headway on goals for other websites I own. None of this started as a "business" idea. It is only fairly recently that my thoughts have turned in that direction.
2) I have toyed with applying and started to fill out an application for last fall. Stuff I have read recently suggests to me they would never accept me, even if I concluded it was a good fit for my goals. But i seriously doubt it would be. I plan to bootstrap it.
3) As above: No. I expect to bootstrap my business plans.
4) My health site is http://www.healthgazelle.com It is the best developed of the sites I have. The others are languishing in purgatory (or perhaps I should say "languishing even worse than this one").
