Gina and I went to Ignite Portland 2 tonight, a collection of 5-minute presentations where the slides advance automatically every 20 seconds.
That misses the essence, though: there were a huge variety of subjects, amazingly good (and passionate!) presenters, and a wonderful community feel (even with the Bagdad Theater packed with 700+ people).
You can watch the videos, and whet your appetite for next time (I’m ready already!).
