I see people who don't use proper punctuation and capitalization as equals most of the time, but I do type with proper grammar and punctuation most of the time, due to the fact that I'm simply used to typing essays and the like.
I tend to like people who speak respectfully, and with proper grammar, punctuation, capitalization, etc, more than people who type like:
ohey alex how are you
This is fine
But, typing like this:
hay alx hw r u
Is a no-go. If they do that, I tend to avoid them later on.
IM TYPING WITH...............a stick................FROM A MEGE-GARLIC-SPEWING LAVA METEOR VAGINA OF THE CORE OF DIAMOLEDS CLASS-123
Yeah, things like this bother the crap out of me.
So, basically, I'm normally quite tollerent about how others type, but typing like:
Hello, How Are You Today
hELLO, hOW aRE yOU tODAY
HELLO HOW ARE YOU TODAY
H3110, H0\|/ 4R3 U 2D4Y
hllo how r u 2day
And the like, bother me.
