For now, free for individual developers to help validate and get tractions, like to see if i can entice free higher level license with exchange for contents/sharings, Doesn't seem to be working.

I like to sell it as team/site license for large dev team in the future. The traction doesn't seem to be there yet.

Because my burn rate is < $150 per year, I have ~1500 users / month come to the site from pure google search alone.

I am just slowly experiment with different features/msg/channels.
