For example, in his latest blog he uses the word "airplane", which as we all know should be "aeroplane". Worst of course is the use of "donut" as opposed to "doughnut" - the item is made out of dough, hence doughnut. Donut sounds like an instruction to be violent.
Nevertheless, I'm sure that Tim's blog would be good enough - just about - to wrap a hot dog in, with sauce and onions of course.
I can only summarise that Tim is sadly suffering from the Dunning-Kruger effect. Thoughts are with you, Tim.
