Tony Karrer summarizes a list of recommendations from Dave Warlick where he suggests that conference organizers should use social networking tools. That's not such great advice, says Karrer. "There's a fundamental flaw in all of these ideas that lead to poor results. The flaw is that it appears that people are quite willing to attend conferences without any up-front effort, back-end effort and probably the minimum effort during the conference." Well, true, but your results will vary depending on your audience - the educamp crowd, for example, is more active than the corporate crowd. But, really, it's just like school or college, isn't it? The real advantage is obtained by the people who aren't there, who couldn't afford the expense. I tend to focus my efforts on people who are not attending the conference.
