I tried to make a self-referencing page, but you need to be able to generate the hash of the page url that includes its own hash...

Not having the time to do so, I leave the challenge here: http://bit.ly/ialoWI

That's not possible because the base 64 encoding is longer than the plaintext. There are 4 characters of text in the URL for every 3 characters of text entered.

If you're willing to jump through hoops and js-compress your content, you can deal with this issue, unless your compressor uses something like crc. That way, you can grow the plaintext faster than the b64 - though you'd still need to do clever things with the url.

That's essentially what you're doing when you are trying to mine Bitcoin :)

until you jumped the api limit :D why not hot swap any shortner?

bit.ly is the only URL shortening service to support cross-origin resource sharing, as far as I'm aware.

The _right_ thing to do would be to build a shortening service designed to handle URLs of arbitrary length. I'm not sure that I'm willing to take on that responsibility, though.
