Fourmii - I'm about a two months away from launching my site after having not one, but two false starts with co-founders that made me decide to go at it alone as well. In hindsight I wish I had a co-founder or at least a mentor who's built and launched a site before. Most of my decisions were off and/or not immediately necessary for the launch. Even choices that I thought were brilliant turned out not as expected. None of this has to do with the product itself, but just getting from development to launch. good luck!
