Who do you follow back on Twitter?

There is almost no limit to the number of people you could follow on Twitter, but when someone follows you, how do you decide whether to follow back or not? I’ve updated my handy cut-out-and-keep Twitter Decision Flowchart for the scientific age. You may wish to add your own block words, so print it in pencil and use an eraser ;-)

Please retweet and share wildly, we should all be applying these principles to boost the overall Twitter signal-to-noise ratio. With apologies to Star Wars fans, a little joke at their expense I was having.
