Tiny Vs Bitly

How cute itty bitty URLs. These would be great in today's instant messaging media. These would keep everything short and sweet. So far I learned to shorten these in a link. But these would work on text messages as well. I didn't care for the bitly because the account was attached to twitter, which I don't use, but still it's attached to public media. I like to control what I put out there. I signed up for tiny and intend to use this regularly.
