Cal Evans, one of the organizers of the php|tek 2011 conference, has some words of advice for anyone out there looking to submit a proposal to a technology conference for the topic of your choice...and have a better chance of being accepted.
Recently on twitter, @johncongdon asked me about proposals for conferences. Specifically, he asked if I had any examples that I can share because he was considering submitting to a conference. While I don't have any examples to share, I can give you some advice on the topic.
He offers some recommended reading of one of his other posts and points out that there's not a single version of a proposal that'll work for all events. He also recommends finding a way to be noticed immediately, whether it be by name or by catchy content.
