grandma, there are any number of fools (especially younger) with a bit of money and a desire to be a "pimp" or a "playah" or whatever they are calling it this week. They live in their mom's basement but drive a leased mercedez with overpriced rims and wear oversized basketball shirts and "party madly". They really believe that they got the life. It is funny to spot them at shows, mostly because they are usually gone by the next show.
Alessandro, just like any business, I don't think it is YOU that the surfers would want to meet, but rather to be exposed to your product. So that would mean probably a decent booth, some booth bunnies, some give aways, promotional materials, CDs with free logons, whatever. I don't think a row of webmasters sitting in chairs signing autographs for the fans would bring in many people...
This sort of thing might start to happen if the programs ever feel that they can market themselves directly better than they can through the affiliate system.
