My good friend, Keith Casey, is once again chairing Zendcon's UnCon. For those who have never attended, it's basically one or more tracks running parallel to the main conference, but with content pitched by attendees — sometimes presented by them, other times presented by others who are knowledgeable in the field.

Why should you care? There are great sessions already selected for the conference featuring some well-known speakers from the PHP world; why would you want to either attend or present at the uncon?
