It seems like there’s a lot of people looking for opposing skill sets (me too!), and we can try to connect people who can help get their ideas off the ground!
If you're interested, feel free to comment here and shoot me a note at email@example.com - I can coordinate logistics and all that other good stuff!
If you look, I think you'll find that there are already a few dozen such Meetup groups in the Bay Area. Granted they are at various activity levels. Quality is not guaranteed. But there are also a lot of co-working spaces and other enterprises also running such "networking" events too. Why reinvent the wheel? Volunteer to improve an existing one.
