Hi @transcript-junky,
I totally agree. I have a friend who has good contents, but he has no patient to proof-read his posts before posting them. I keep reminding him about it and hope it will eventually penetrate his impatient armor.
Its funny actually that even when I was dating, when someone sends me a and email or a text full of misspellings, I would be completely turned off and mark that person as a "Not suitable".
English is not my first language, but I feel that if a person don't care about how they say or write their words, then I start thinking of them as "careless" and not so much trust-worthy.
I would like to write a post about this (will link it to your post of course). I hope you don't mind :)
Thanks for the tips
