Hmmm, "the lost art of effective writing". I think that now we must beware of adopting a different set of clues to form our judgements.

In the everyday world we pre-judge people by age, gender, color, appearance and a host of other clues. Now I find that I have to be careful not to judge others by their choice of words, their spelling and even by the length of their messages.

Some of us aren't as gifted as others in their writing abilities. This can be due to many factors other than innate ability. Some of us are trained as engineers or scientists and can sometimes come across quite terse, others may have dyslexia or maybe physical disabilties which can hinder typing.

Whilst some may "strive to improve their language skills", others may have a constant struggle to be able to write anything at all.

I don't pre-judge people by their writing abilities any more than I would judge them by their engineering abilities.
