That's nice. I've been using the following piece of sneaky ghetto code to take advantage of Google Toolbar's URL shortening API:<p><a href="http://codepaste.net/48qfb7" rel="nofollow">http://codepaste.net/48qfb7</a><p>But now I'll be able to shorten URL's with an official API rather than using a hack. I don't know why Google didn't make a public API from the start.
If I tries to shorten the url of <a href="http://google.com" rel="nofollow">http://google.com</a> several times, goo.gl always give back different result. I just wonder will goo.gl merge theses url together sometime later?<p>This interesting found implies how goo.gl is designed. They prefer writing directly to avoid duplication check and random seek caused by the check. And they though most of the urls are cold so it is not essential to merge them together to keep the hot cache small.<p>Or they assume nobody wants to play the system in this way. :-)
Any insight to whether this would be rolled into a Google Apps for your domain offering?<p>We're using yourls.org currently for our short domain name and would welcome ($) the opportunity of offloading the traffic to Google's servers.
