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.
From the FAQ: AirDropper is best suited for professionals who need to make sending files securely easy for the sender, including designers, lawyers, accountants, or consultants.
I don't know if it came up in the earlier discussion, but these types of people are likely to have several clients and projects going on at the same time. Rather than dump everything into a common AirDropper folder, would probably be useful organizationally if the person requesting the file could indicate a subfolder somehow, so when the client uploaded the file it would get dropped into that subfolder within the parent AirDropper folder.
Of course as soon as you implement that, people might want support for an infinite hierarchy, but I'd think one level of subfolders would cover most needs.
Yeah, that's a big issue. You can actually specify a subfolder when you create the request. It's the last field on the page. We probably need to make that more obvious.

Thanks everyone!
