Seems pretty cool. I was actually thinking of building a similar 'accountless' file upload and sharing service, but this one is a lot better than what I was envisaging.

Question - would you, in the future allow uploading to configurable destinations, e.g. my own S3 buckets? Also, do you track the number of time a file asset was downloaded from your service so that the original uploader can check activity stats?

EDIT: Feedback - when I scrolled to the bottom of the home page, the "There is something I have to tell you" section is duplicated under itself.
