Today Is...World Letter Writing Day

It has been said that the art of letter writing has died but if i was writing a letter in Middle England times then it would read very different. Firstly i would be more cautious about the subject matter as i'm not sure how kindly the very head choppy King Henry VIII would take to his subjects writing letters mocking his obesity, his love life or his crippling gout and 16th Century Keyboards would have been laid out very differently as back then the English language was a very different beast. 
It appears that since people like Chaucer 600 years ago put quill to parchment we have gained the letters J, U, V and W which he never had access to so we may have 16% more alphabet than him but the alphabet is a constantly changing feast.
The English language has frequently been referred to as one of the hardest languages to learn because of such nuances of the language which allows for such confusing things as to, too and two or rain, reign and rein. Aonethr qiruk is taht as lnog as the fsirt and lsat lterets are in pacle, it is still readable although your spell check may explode.
Outside of official documents or projects where the perfect English is required, I have never been much of a spelling nazi and some people argue that mispelt words should be included as 'variant spellings' and accepted into everyday use, not corrected and although i have my reservations, they have a point.
The English language has changed and adapted its spelling over time. For example musick mutated into music, rime into rhyme and we nowadays write fantasy to the original phantasy and show to shew so changes to how we spell is an ever evolving process.
Others argue that turning a blind eye to common misspellings such as 'truely', and 'argument' is the slippery slope towards the American style of spelling which is a slightly simplified version of English, such as color, dialog and favor and British kids should just learn the correct spelling rather than adapt the language around there shaky grasp of spelling.
My reservation is that lazy students will invariably shout 'spelling variation' when they get pulled up for writing 'commited' or 'imediately' and that just won't do. How can we act all snooty to Americans and Canadians for their spelling if we dumb down our own!
