twi.bz shortens web addresses without completely obscuring where the link ends up. By keeping part of the domain name in the twi.bz link it's possible to instantly see the site you'll end up on by clicking the link.
For example, my book The Geek Atlas is available from Amazon.com at the web address http://www.amazon.com/Geek-Atlas-Places-Science-Technology/dp/0596523203. That's 72 characters! Half the length of a Twitter message and easily messed up by broken email programs.
If you visit other web address shorteners and shorten that address you'll end up with links like http://tinyurl.com/c38594 or http://bit.ly/J0BE. It's impossible to know where those links will take you.
With twi.bz the short address for The Geek Atlas is http://amazon.twi.bz/a. Instantly you know you'll be taken to Amazon.com.
For any link you make part of the domain name will be included in the twi.bz link. For example, a link to Google will start google.twi.bz, a link to a story on CNN will begin with cnn.twi.bz and a link to a picture on Flickr will begin flickr.twi.bz.
Yes, just drag the following link to your browser's toolbar: Shorten with twi.bz. Then visit any page and click that link to shorten that page's URL.
Yes, just add /explain (or /e) to the end of any twi.bz link. For example, http://amazon.twi.bz/a can be turned into an explain link by writing http://amazon.twi.bz/a/explain or http://amazon.twi.bz/a/e.
twi.bz was made by John Graham-Cumming. It's yours to use for free. All links made with twi.bz are permanent. twi.bz tries to make URL shortening more transparent, but if you click on a twi.bz link and see something you don't like I disclaim responsibility. twi.bz doesn't warrant that a link is safe, it just tries to make them more transparent.
Privacy note: twi.bz doesn't intend to keep the URLs it shortens private. In future twi.bz may publish of list of URLs. So, if you use this service the URL you enter may eventually become public. Don't use it for URLs that you want kept private.
A teeny weeny internet bearing: a short link that takes you somewhere else on the Internet.
