Ask HN: What should I present about at SXSW?
Website Optimization Basics: I wrote a post a few months back that was popular on HN, about how I reduced page load time by 75% (http://www.kadavy.net/blog/posts/wordpress-optimization-drea...). I would boil down the technical jargon to simple language. It would be a dual presentation with the engineer that gave me most of the advice I used.
Reverse-Engineering Visual Design: I would explain some of the classic principles and methods that designers use to make the decisions they do when designing for the web. I presented on this at BarCamp Chicago a couple of years ago (http://www.kadavy.net/blog/posts/design-for-the-coders-mind-...), so I have something to start with, but it still needs more juice.
Everything You Already Know About SEO: the basics of SEO are stupidly simple, and widely known, but there are many misconceptions and unknowns. I would condense and explain all of the best practices and things that we do know about SEO, and how to use them to grow your business.
How to Get a Date Online: I have an alter-ego through which I give online dating tips (http://onlinedatingmatchmaker.com). I would talk about how to best represent the interesting aspects about yourself, present communication techniques for opening with matches and securing dates, and present data from studies that suggest provocative things, such as why you should lie on your online dating profile (http://www.onlinedatingmatchmaker.com/lie-online-dating-prof...). I actually got a personal message from Hugh Forrest only minutes after submitting this presentation idea last year - about how much he liked the idea - but I guess it didn't make it through the selection process.
Do any of these sound good to you?
