Hi, Sophie. That's a good question, with broader implications for our efforts. The short answer is that after about a year and a half of hosting meetings, we've had two attendees. In terms of numbers, this isn't taking off yet, at least in Pittsburgh.

That said, I continue to see advantages in the continuing education/learning club approach to GW meetings. I typically learn GW things myself at the lectures, it supports local green instructors and groups, it removes pressure from the local leader to host a great discussion, people can try out a GW meeting in a safe and public environment, and so forth.

So, at least for the near future, I'll plan to keep hosting these meetups, even without expecting a large (any?) turnout. It seems a worthwhile thing to do, and I certainly would not want to discourage anyone else from attempting this sort of effort.
