I've often thought about building something like this into HN itself and having a 'meet' tab at the top. There are so many people, me included, whose lives have been changed by HN. I would love to find a way to encourage more positive effects in the real world. Not sure exactly how this would work, but it's encouraging to see the community taking up the cause again, and I'll be interested to hear about how this goes.…
On a related note, for any HNers (or hackers) in/around Austin, TX that want to meet, I'd be happy to help organize a meetup in Austin, if you're interested in connecting.
