Just tried it. I like how fast this is! It's a good alternative to dropbox for a quick image upload or something. It would be nice if it auto copied just the url.
I would also like it if the file stayed hosted longer than an hour. Say I want to email the link to a friend, but the friend doesn't check their email for 3 hours. If they click the link the file will no longer be there. Having the droplink icon in the top menu bar would be great, instead of having it in the dock.
That being said, the text and icons are really hard to see. They blend into the white background too much.
*edit: The password is showing clear text. Why?
