I appreciate the Apache license protections for those who use your software; that's not enough.
You need to make a written pledge as an organization that any patents you make on the work you do are freely licensed. Right now, you're putting everyone in the space at risk. We don't know if you're going to overreach and patent distributed social networking, or user profiles, or whatever.
Fortunately, you have one of the smartest patent defenders on the planet on your board.
