A small overview of what DuckDuckGo can offer you in the way of private communication over the open-source protocol XMPP.
What is XMPP? XMPP (sometimes called Jabber) is an open-source instant messaging protocol which allows you to exchange instant messages with other users. Unlike normal messaging clients like Yahoo! Messenger, ICQ and MSN, XMPP's open structure means there are many different XMPP servers and clients for you to use while still being able to communicate to others through the same standard. If you are new to XMPP, just go to our other blog post about how to use Pidgin with our XMPP server. There, you'll get a brief overview of how to get an account--which you can use to communicate with all other XMPP users around the world.
