But you did nail item #1 - I was primarily interested in learning/experiencing, and secondarily interested in adding value. That's one of the reasons I lost motivation and shut down the site, it is extraordinarily difficult for coupons/discounts to add value to businesses across the spectrum of business. Some businesses it works great for, many it doesn't. It was when I had that realization that I decided to end it.
I did spend time (sorry, probably not "much time") brainstorming business ideas that actually would add value to the businesses I knew, and I think some of those ideas are good, but just not feasible for me to do alone, so I'm not even pursuing them either.
I have a friend that has spent _years_ and tons of his own money working on his startup, and it's still struggling to succeed. I learned a lot from him as he was my mentor through this process. I hope his endeavor takes off, but it's a long road, and he has worked incredibly hard. I can connect the two of you if you actually want to talk to someone like that.
