>>23Yes, this mistake (using an instead of a because the word starts with a vowel but is pronounced as a consonant) indicates low-intelligence. A person of high-intelligence would be able to 'sound-out' each word he types prior to typing it -- at such a speed that it barely registers in his consciousness -- while those of low-intelligence are unable to do this at a reasonable speed and thus dispense entirely with sounding-out words or even fully grasping their meaning. These are the people that read WTF as "w.t.f." instead of "what the fuck". These are the people who do not possess the intelligence to seamlessly differentiate between they're and there while typing.
