HOWTO start a flashmob

Here's the latest Instructables HOWTO to tie in with my young adult novel Little Brother, which tells the story of young geeks who use technology to restore liberty to post-9/11 America.

This week, it's HOWTO start a flashmob:

Timing is everything
This refers back to the whole participation thing. If your event is spontaneous in nature and just requires people to show up at the same time and do something goofy(say, gather at a subway stop and follow the first bearded person you see as if they were Jesus), they won't need much time to prepare. The ideal time for this sort of event is at the end of the workday (between 5 and 6PM) during the week as a) the streets are more crowded and b)participants are more available. For whatever reason, Thursdays seem to be most effective.

If you are planning something more elaborate, like a Costumed Rampage, you want to give people at least a week to prepare, and preferably two. These events are most effective in heavily populated shopping and tourist areas, so Saturday afternoons work best. Note: these often turn into drunkfests.
