Kayless - I taught typewriting and have many certificates to show my proficiency. I am also quite good at spelling and always proof read my posts - but still occasional typos slip through, so you can rest assured you are not the ony one who makes the occasional mistake. Take no notice of Sgt.Rock - he is not perfect, no-one is.
Just people doing typos. On a telephone keypad, which is how most people Tweet, the F is 3 and the H is 4.
This is a non story. Anyone can do a typo and that does not make them stupid, but anyone who is taken in by this nonsense and thinks it is genuine news and worth posting about is STUPID!
