I spend around 18 hours a day on Facebook, for work and leisure. Recently, I've been noting down the most common spelling mistakes I see on Facebook. Some of the spelling and grammar mistakes people write on Facebook are unconsciously funny; others are just plain sad.  Anyway, here's my list of the "Top 10 Spelling Mistakes on Facebook". (But be warned: the following list of Facebook fails contains some swear words).

Funny mistakes by others, or even your own funny mistakes, can help you to improve your vocabulary — so long as you learn from those mistakes. For example, the new book The Funny Dictionary is a collection of student bloopers, arranged in alphabetical form. Most of the funny definitions in The Funny Dictionary come from answers school children have provided to English exam questions. But in order to find the book's definitions funny, you must understand the child's mistake. For this, you need a good vocabulary. Study the following extract from The Funny Dictionary  to see if you can work out the source of the child's confusion and why their definition is funny. It's much better if you can work out the joke for yourself, but we've given you some examples to help anyway.
