I've met only a handful of posters face to face, but thats because of my own paranoid tendency to keep myself unknown. The ones I met (even a couple of times) were genuine and really friendly and accepting. I was even invited to a party, but I declined for a couple of reasons. One is because I feared pictures would inevitably get out onto the web and another is that one of the attendees would know me and although she'd very likely keep things mum, stuff would get out. I'm trying to fade without getting DF'ed.
I think fakers are the exception. Maybe a few blowhards and those who exaggerate some of their life's drama. And there was only one poster who seemed overly curious in trying to get a few people's real names.
