ICST MyBoard

Today I presented at the e-Science Institute in Edinburgh event "The Influence and Impact of Web 2.0 on Various Applications". Following that an attendee pointed me towards ICST (The Institute for Computer Sciences, Social Informatics and Telecommunications Engineering) http://icst.org and their MyBoard project http://icst.org/myboard/ which has some overlapping aims with LinkSphere.
I have now registered with ICST, and MyBoard is really a list of my interests, I can change what I tick but there is no free text entry. I haven't yet worked out how to discover people who share my interests or how to communicate with them.
