Facebook has opened up early registration for their developer event, f8.

The f8 ’08 sessions cover three different tracks with four sessions per track. These are actually pretty interesting sounding sessions. Early bird registration is only 150 dollars, to learn more about sessions and registration costs visit the f8 registration page.

This is a one day event so if you are planning on going to SMX Local / Mobile you can pull it off (f8 is the day before SMX). Look at the tracks below for f8, and notice the business and mobile tracks. hmmm.
