It seems like each four minutes there's a new event happening in Boston proper or across the river where I sit typing right now.

These events range from knitting circles to test drive tweetups, and the thing these events have in common is that they're increasingly organized via social media tools.

So imagine my surprise when I found out this morning in one of the first sessions at the Social Technology and Education Conference at Harvard University, that this very conference was completely organized without any traditional marketing.
