If you have not gotten your proposal for a talk, tutorial, or poster for PyCon US 2011, you have until tomorrow! If you have never submitted a talk, do not feel intimidated about presenting at PyCon. People are very friendly there so you don't need to worry about a hostile presenting environment. And if you are not sure what to talk about, what did you discuss with your co-workers last? If they found it interesting then the PyCon crowd might as well.
