What sort of content were you thinking of? Would it be an introduction to the site and how to best to contribute to it? What makes a good question/answer, etc...
I was thinking of submitting a SFSE talk with a different focus.
I'd go back through the questions asked and answered from the previous year (or so) looking for anything that really stood out from a technical perspective. Sort of a highlights reel.
We could go through the question and answer looking at how it worked and why the answer was interesting. There would plenty of opportunities to fire up an org and run through demos. So less focused on SFSE per se, and more on the content of the answers and what made them interesting. If fact, it could also source content from other forums and blogs. I'd need to figure out how to attribute each part to the person(s) who developed the content and probably check with the author first, especially with blog posts.
Would be happy to have a co-presenter.
