Is it me or doest this read like it's half an article? I got through to the end expecting it to be about something that you can do with XMPP and Jabber, rather than a rather basic primer on Jabber and XMPP themselves.
I don't have a problem with it, although it would've been nice if the title had made it clear that it was a primer.
The article was originally written as separate article to appear alongside the main article I wrote for .net Magazine.
The main article is about creating a Google Talk bot with Node.js so if you want to create something with XMPP then please have a read through of that article: http://news.ycombinator.com/item?id=5175913
Also when I submitted this article to Hacker News I entitled it "A short history of XMPP and Jabber" so I am not sure how or when it got renamed.
