Page Tweet is a unique url shortener. I’m just going to quote from a great blog called Demo Girl (you should visit her blog because she has a screencast showing how to use Page Tweet) to describe it:
[It]allows you to shrink a URL for sharing on Twitter and other social networking sites, but also allows you to add your own 140 character message to the actual link that you’re sharing. Your message doesn’t appear in your Twitter updates with the link, it appears on the actual site – allowing the people who click on the link to see why you brought them there in the first place.
I could see using it even when you’re not shortening it for a network like Twitter.
I’m adding it to The Best Ways To Shorten URL Addresses.
