> Storing a document in a URL is nifty, but not terribly practical. Hashify uses the [bit.ly API][4] to shorten URLs from as many as 30,000 characters to just 20 or so. In essence, bit.ly acts as a document store! [1]

bit.ly et al. seem to be able to get away with being agnostic processors. I'm surprised there haven't been more stories about their services being abused.
