this was close to a dollar years ago when they didn't have nearly as much promise. David is not a stupid guy and has made a living taking unsuccessful companies and turning them into multi million dollar operations. This is his pet project and he disclosed a long time ago he thought there was so much potential here he was going to hold onto this one and he has invested a ton of his own time and MONEy here.
Do your own DD and if you decide to come aboard, welcome :)
