Real citation: "Texting is a truly tricky form for the ironist - very brief texts are difficult to make ironic simply because it's difficult to inject many layers into seven words. However, if you write a very long text, because it's such a bugger to do, your extra effort suggests a sincerity - an undudelike urge to be understood - that sits all wrong with the irony. To get round this, forms like "(!)" and "Not" and "have evolved", but they're pretty dumb and basic."
