I went to a number of events, the organizers seemed more concerned about making money more than anything else, or inviting members to well orchestrated 'setup' events just to attempt to put the person down and then take advantage of them. In particular one event organizer in Toronto Sarah demanded money for events one failed to attend even when the emails were unsolicited. Now I am not saying that all the meet up groups are the same, but I would say there are quite a number that only want to take advantage of new members.
