Newmindspace in Toronto/NY has an excellent post about what is not a flashmob. I'll admit, I have big dreams to creating events similar to the ones they do in Toronto and ones I remember from SF days. It's damn hard here in LA though - but not for a lack of trying.
We’ve had the pleasure of communicating with Mobile Clubbing over in London, who are responsible for, among other things, holding the first “exclusively internet-promoted massive pillow fight” and hosting a number of very successful public dance parties, with numbers up to 4,000! We are very enamored with them and certainly, their inspiration to our events is unmistakable. Their most recent event, just a few days ago, is being heralded as the largest flashmob ever.
However, I am hesitant to call their events “flashmobs”, and I hope they will be one of the first groups to abandon the word. This is part of a longer, ongoing struggle that will probably culminate in an essay on the subject, but in short, flashmobs are dead.
I've considered doing some mobile clubbing things... more like mobile clubbing - inspired from the Streetwars Moving Truck Rendezvous point. I've got other ideas on the back burner, which will hopefully get moved up soon.
