Can this work? I think it can. Of course people are 'shy' about disclosing who they are. A few ways around that:
* Make it a costume party
* Bill the event as "GNI members, readers and friends". That way, people can opt to say that they are readers or friends of members, and not posters. Of course people would be free to say that the post on GNI and even state their GNI 'handle'.
* Organize the events by city. So, for example, you could have "Toronto GNI get together", New York GNI get together, Miami GNI get together.... You get the idea.
* It might help to improve understanding, take the temperature down and even build some solid, long lasting friendships. From what I see, the overwhelming majority of people here are very good - even though their bark is often worse than their bite.
