I'm talking about Socialtext Eventspace, which sounds so amazingly cool that I wish every conference organizer would at least check it out. But it's also a little scary, in that it puts a lot of the control over what's said about your event in the hands of attendees, and you know, there's usually more than one in every crowd that will just kvetch endlessly. But you know what? They're doing that already, and you can edit—it just means someone has to be paying attention. But shouldn't you be paying attention anyway? To see what this is all about, check out the Eventspaces for the Web 2.0 Conference, Supernova, and the PC Forum.
If someone reading this has used Eventspace, please e-mail me about your experience with it. I'd love to learn more.
