Ok, so this post isn’t photo related, but if you use Facebook for your photo business, this may be of interest to you.
You can now chat with any of your Facebook friends using any instant messenger that supports the Jabber/XMPP protocol such as AOL-AIM, iChat and my personal choice Pidgin.
Getting started is easy. In most clients, add a new XMPP account, if you choose a Facebook username that’s the name you’ll use to log in and use your Facebook password. The chat server is chat.facebook.com. And, if you’re asked to input a port it is 5222.
You can read more about it on the Facebook blog and get examples for setting up with your IM client.
