Come on down Paul Jones the price is right

Crass, bold and rude?

I'd say it was more like dishing out what was deserved.

Internet convention be bollocksed - it's an excuse for some knobs to make themselves feel superior.
No harm comes from reading in capital letters, it's nice and bold, clearly and easily understood.
I've been hand writing in capitals since I left school, no one has ever complained that my written work is shouty, the only important thing is for all the information contained within it to be accurate and easily understood.
I can't see why anyone should get their knickers in a twist over it being used in a poxy canal forum.

I’m not saying the reposts weren’t deserved, just that the whole tone of it doesn’t strike me as being from some “social media virgin”. Block capitals are slightly harder to read than lower case. Although I too tend to hand write in block capitals, but that is because my joined up writing is illegible.

I'm not convinced about Mr Jones being from here though.
We share your last sentence in common though - freed from the tyranny of school teachers demanding lowercase at the very least and joined up writing being of greater preference I adopted uppercase pretty smartish at Tech.

Patience is a virtue.
Let the fella feel comfortable with his spellink first, then progress onto punkchewation.
It's a bit like anyone learning to fly and navigate at the same time. Everyone has different mental abilities, just some take a little longer to get past the finishing post than other's. But if they're encouraged, they soon catch up.

What you need to understand Mr TellyMackus is that a person may be very intelligent in many ways, yet have difficulty with written language, the English language particularly being a difficult language to master as it does not follow basic linguistic rules, i.e. that every written letter is always pronounced in exactly the same way. Russian is a beautifully simple language, very easy to learn, simply because it has not been bastardised in the way that English has, mostly by pretentious people in the Victorian era who felt that their superior education enabled them to make "improvements" to what had come before.

Anyway, here's a rather pleasant song about dyslexia for you to enjoy, performed by a very successful, if dyslexic songwriter, Natalie Merchant.
