I’ve been to quite a few conferences in the past few years and one thing that is always a contention point is how to gather feedback from presentations. Solutions that I’ve seen go from feedback forms and putting votes in a ballot to high tech iPhone apps where you can register your impressions.
At LESS 2011, the organizers ditched the standard forms and went with simple post-its for feedback.
Instead of answering multiple questions, all you had to do is to grab a post it (available in all chairs) and stick it on the right place on the door when leaving (picture below). If you had anything more to say, you could write it in the actual post it, which were then delivered as they were written to the presenters.
That’s it! Simple and effective.
