I have at least five different IM accounts, not including Skype. So while I found the Facebook IM feature relatively cool from an embedded web app perspective, I found it nearly impossible to use regularly - the service required FB to be open in the browser, and incoming message alerts would be hidden if multiple tabs were open (I have 14 open as I write this), causing messages to be buried until the user returned to the tab.
Adium, the most excellent consolidator of IM accounts, announced they have integrated Facebook Chat into their platform. Of course, to use Adium, you need a Mac. But you probably already knew that. Now, if only Skype would open its platform up….
