Sounds like a really cool idea. How do you organize the meetup and promote it to people if it ends up being random people? Do you set it up on meetup.com and have a theme at the minimum?

I've been to a lot of meetups and it's definitely hit or miss and obviously depends on the sociability of the people that show up. The better ones I've attended are generally ones where people aren't trying to network for work purposes and are there literally to just socialize. The networking ones I find very dull as it's people just talking shop and career and if you've nothing to offer them on the career front, they move on quickly.
