What a great idea for an event organizer... I've often wondered why event planners don't come out with "official" tags for people to tag entries on blogs, photos on flickr, videos on youtube etc... (many people, including yours truly post photos and create our own tags) but here's a cool idea that I never thought of.. what about networking groups on LinkedIn, facebook and others? That's exactly what Nokia is doing for their Nokia World event... attendees can coonect by being accepted into these special groups... nice idea!
They've created several groups that will enable attendees to connect... they have the Nokia World Facebook group, LinkedIn group, flickr group and others... nice job!
