AJAX and Flash mistakes

I gave a little talk on “AJAX and Flash mistakes: lessons learned building SlideShare” at SXSW08 last weekend. The audience was great, and the conference in general was a helluva lot of fun (as always).
I talked a lot about the interplay between AJAX and server-side performance … how AJAX often seems like a performance solution, but often introduces new problems. I also talked about the need to design entire processes, rather than simple modal dialogs (which are so easy to design that your design skills for building multi-panel flows can get quite rusty if you aren’t careful).
