Hillmap is pretty sweet. Totally nerding out about it. Geospatial stuff like this is what I really enjoy. What are you looking to do with it in the future?
Mostly I plan to use it to ski and climb all over Montana!
Its actually a few years old and I was thinking of trying to make it more of a money maker at one point but other interests have proven more profitable so I'm not sure I'll ever really push for it to become a true business.
I and many of my friends do get a ton of pleasure out of trips planed with it which is its own reward.
Might be hard to really monetize anyways, its really nice that you keep it available for people to use. If you don't plan on making more money from it, you could always open source it, and let others contribute too for fun.
