I was thinking about hosting an on-line chat event... Who would be interested in joining in a scheduled chat with other Geekzoners, and possibly some guests?

This would be with an on-line chat tool, I am investigating one at the moment.

Any suggestions for topics? It would be a one hour session, with suggestions from participants, advices from guests and a Q&A at the end.

Worth doing it? Would you invite a friend to attend?
