The large arrows are inputs. I will primarily use Audioboo (for sound of course), Tweetdeck for text tweets, and Posterous for pics and blogs. I have turned off outputs from all the entities in the central column. i can post straight into any of them individually of course. I'll use ping.fm mainly for microblogs because I've got the widget on my Google homepage and it makes that very fast.I still have to set up an archive for tweets and boos - never thought of that until documentally mentioned it. I will probably set up a second Tumblr for that.
Ok, now all that remains is to test - so this is my first Posterous blog - and send!
