It seems that Matt Mullenweg and Peter Saint-André have been kicking around some ideas about how WordPress and Jabber could work together. I used to have my blog set up to send me an instant message via Jabber every time a new comment was posted. I lost those notifications in an upgrade a while back, but I’ve been thinking about redoing it as a plugin. About two years ago, I talked about setting up a pubsub component that would let people subscribe to the comments on an article. Pixelcort has an idea to do new post notifications. And of course, you could always try to go in the other direction: how about if you could post articles or comments from your IM client? There are lots of possibilities for tying blogs and IM together.
Yes, I know it’s more appropriate to call it XMPP, but I’ve been tinkering with Jabber since before XMPP was formalized, and old habits die hard. In any case, I hope that maybe one day Jabber might be able to do some sort of public relations push similar to the recent Firefox campaign. If a few key bits of the protocol can be standardized, and a few really good clients can be polished up, it could make a real push to replace things like AIM, ICQ, Yahoo! Messenger, and MSN Messenger. Julian Missig had some thoughts in that direction recently.
