XMPP Provides easy and clean ways to build XMPP Bots, as I showed on the previous post, we can use Google AppEngine to create 24h online, zero-maintenance Bots. Yes, I don't need to host this. Google is doing the job for now, for free, let it be.
You can use the xmppguru extension to Short URL simply add it to your GTalk's / Jabber Contacts: email@example.com
Examples of general usage
To request a Short Version of your URL just send a message containing the URL.
Chat Message: http://pixagle.appspot.com
firstname.lastname@example.org: http://zapt.in/D5 -> http://pixagle.appspot.com
Chat Message: xmppjingle.org
email@example.com: http://zapt.in/D1 -> http://xmppjingle.org
This is quite handy, avoiding all the hassle to visit one of the other URL Shorteners just to have a smaller URL.
