Hey, though there are some shorteners around, i made my own with these cool features:

- easy to remind URL: btcENco.de (that's "btc encode", just in case  )

- gives you (1) a short URL (2) a token to decode on the site and (3) a qr-code

- great privacy with nothing stored than the provided address and the generated token

- no ads, no Google Analytics

- lightweight, great for mobile devices

Just head over to btcENco.de


added (June 08, 2011):

- second QR code (now there's one with the address and one with the short URL)

- a set of userbars (5 by now, more to come)

- Bitcoin address already in db will always produce the same link (no duplicate entries anymore)


added (June 10, 2011):

- an actually working address validation (kudos to theymos for http://forum.bitcoin.org/index.php?topic=1026.msg184508#msg184508  )

- userbar #6
