There are two different types of school. There’s an old fashioned school (I am not saying that this is necessarily wrong) which talks about the demise of good spelling and grammar and links this with a problem with modern technology. There are many websites and many blogs discussing this topic.
On the other hand, there is a modern school which says that the most important aspect is the fact that the reader understands. For example, there was a test at Cambridge University which goes as follows:
Aoccdrnig to rseerach at Cmabrigde Uinervtisy, it deosn’t mttaer in waht oredr the ltteers in a wrod are, the olny iprmoatnt tihng is taht the frist and lsat ltteer be at the rghit pclae.

Perhaps you are wondering how you can read the above so easily?
The point of this line of research is that proficient readers read most words (except very long ones) principally through the first and last letters and a rapid recognition of the general shape and content of the entire word. That’s why we typically read misspelled words with no trouble.
I wonder what you think because ultimately it is very important for all our marketing if we understand how the receiver of our marketing messages thinks.
