Checked out the site. An hour I later tried to remember name to tell a friend but couldn't remember it. You don't have munchery.com, so I don't know why you're going with that name. You might want to get a better one. IMHO.
1) Dropbox is/was not a webapp. The site is just a place to download the app once or twice (for most users).
2) Dropbox is an extremely good name, so living with getdropbox.com at first is understandable. The equivalent in quality would be something like munch.com, in which case gomunch.com would be reasonable at first. The domain gomunchery.com is a double compromise.
