In a generation, electronic communication has grown from initial inception to ubiquitous, the fastest adoption of any technology and supporting behavior change ever.

I have heard all sorts of babble about why this is, but it seems to me that there is one simple reason, the removal of the transaction costs in earlier forms of communication.

It now costs virtually nothing to send a message via email, and no more to broadcast that same messageĀ  to hundreds, often thousands of geographically spread recipients.

The downside of course is that our in-boxes have become clogged by stuff we do not want, and did not ask for, but the delete button is pretty effective.
