Here’s an image that’ll glaze you over. Brian Solis and JESS3 have produced a chart of the Twitterverse. Twitter, and everything having to do with tracking Twitter, ranking Twitter, better organising your Twitter or incorporating Twitter into different media are (hopefully) represented in an enormous visual that, for all its rigour, is likely missing a service or two because more are born every day. (Remember the birth of Klout? That seems like just yesterday.)
To make life easier, the apps are arranged by type, spiraling out of the centre of the sphere: branding, geographics, interest graph, event management, live streaming … you name it, it’s been categorised up to the furthest reaches of causation. You will probably want to print this out and put it somewhere within distance of your index feature, because, if you’re doing any kind of strategy touching upon wireless connectivity, you have no idea how helpful this is gonna be.
Thanks to Romain Guillot for the tip.
