I love the “law of two feet” used in unconferences

The law of two feet

This rule states that if you are not contributing or adding value to the session you are attending, you can move elsewhere. There could be a session in which you can contribute more.

In fact, one of the peculiar characteristics of this conference is the freedom of moving among sessions, which is not perceived as rudeness or lack of respect.
