Right on.

A while back I logged into a Twitter account that had been dormant for a couple of years, since it appeared that some good friends had started using it more actively. As a result, I started getting email from Twitter once a week like clockwork. Clearly not a "our algorithms determined that something interesting happened" message, but a "our algorithm determined that you should get a message once a week, let's pick a random event from your social graph" one.

The main result is that I know better than to ever log in again and become a marginally engaged user worth spamming.
