We made a FAQ page for AirDropper based on all the feedback everyone provided earlier in the week. (http://news.ycombinator.com/item?id=1613574) You really helped us start to understand which benefits were important to emphasize. We'll definitely be keeping the feedback in mind as we work to improve AirDropper.
The FAQ is available here: http://www.airdropper.com/faq
Thanks everyone!
