Well I seem to have volunteered to talk for an indeterminate time on A/B testing at LA.pm on Thursday next week.
I've never given a presentation like this before. And my first one will basically be a math talk directed towards programmers? I could have picked an easier topic!
Ah well. I've long thought that the techniques of A/B testing weren't widely enough understood. This will be my chance to correct that. I'll just have to find somewhere to put my slides on when I'm done. As for presentation software, S5 looks like it does what I want.
Wish me luck.
