Half the places are now gone, and people continue to signup, but we can not continue to rely on this just happening on it’s own. BarCamp is made by the people attending so we need to spread the word. The first rule about BarCamp is that “You do talk about BarCamp”, and the second is that “You do blog about BarCamp”. If you know someone who would be interested in attending then let them know. Post on Twitter that you are attending. Write a blog post about BarCamp.
