The call for speakers for cf.Objective() 2012 is now open. You can either submit proposals for something you'd like to talk about or make suggestions for topics you'd like to see someone else talk about.
Right now, I don't know whether I'll submit any proposals. I'm not sure what topics I'd like to promote. I don't want to do another "Intro to FW/1" (but I'd be very happy to see others continue to promote FW/1 - and I'd hope someone will mention DI/1 alongside FW/1!) and most of the non-FW/1 stuff I've been doing has been Clojure, at least in terms of open source projects. If you have ideas for something you'd really like me to submit a proposal on, let me know!
