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.

Having covered upwards of a dozen technology events in the past year, there's been one constant at each conference or seminar - each leans unabashedly toward the magic of social media tools and techniques.

As was true with the Cable show at the Hynes this winter, the buzz at Enterprise 2.0 is all about building communities, leveraging Web tools, and lowering the barrier to communicating with your chosen networks.

What's that mean?

It means that businesses, as always, are searching for the low-hanging fruit in their efforts to find new customers and build their company's success.
