Back in July I went on a tear about a conference experience I had (as an organizer and participant). Ilya Vedrashko from AdvertisingLab offers a more constructive take on improving the usability of conferences. Nice ideas on content (shift discussion control from panel moderators to attendees, have speakers debate controversial issues) and logistics (a place to leave messages for attendees, larger font sizes on nametags, more useful totebags).
