Christopher Carfi drew my attention to David Armano's Social Systems graphic. What I particularly like about it is that it describes where I spend most of my time online.
What's missing here is the web analytics piece. While Twitter, Flickr, YouTube, SlideShare, Facebook and others build-in simple stats tools, I spend a respectable amount of time also checking the stats of RSS feeds (Feedburner), rankings in Technorati, and (if applicable) visits/pageviews in Google Analytics.
It's an ecommunication ecosystem out there and analytics MUST be part of the conversation.
Now, what we really need is someone to build a free configurable online dashboard application so we can manage all these sites and tools!
