Help Design the Learning 2005 Social Network

How many conferences actually ask you to help design the interaction that will go on there? Well Learning 2005 (L5) will. [Full disclosure - I work for the the MASIE Center] We are using a social networking tool at L5 this year from a company called IntroNetworks. What is really cool, is that the tool allows you to quickly search through members of a community by narrowing the population along the lines of what interests you. So we are asking for some help in comign up with the right words to describe those interests. Check out the intro and design challenge here.
