Ah, cool, the grammar and lexis police.
I mean, "ah" isn't a word either. Or wasn't always. It's like (or is) onomatopoeic; an expression of a sigh.
I mean, your yardstick here is fanfiction dot net. It's fan fiction. Written to whatever standards the author is able to muster. Unless the person is proclaiming some kind of excellence in the English language, you're being elitist.
Fanfiction.net is an example. I've seen books on Kindle that have so many typos and formatting errors that they're unreadable.
Proofreading and editing are things most people don't bother with, and it's not only people who post on social media. A browse through my news site on any average day will reveal plenty of articles that weren't proofread.
People got lazy over the past several decades.
So back to "u" for a second. It's an abbreviation. From "text" speak, which arose in the early days of mobile phones where people are charged by the character for how much an SMS costs. I'm sorry if you already knew that, but that explains why people use it. People had valid, inarguable reasons to come up with it and use it. Text speak literally defined a generation (or more). It's habit. You can call it a bad habit if you want, but your anecdotes about how people are typing online is not indicative of baseline literacy or handwriting skills. And you're using it to justify a bad habit of your own - judging people for how they communicate on places like Facebook. That's not a writing site. It's not peer-reviewed. It's social media.
I don't own a mobile phone. I have never willingly used one.
The Facebook site I post on is the one belonging to my MLA (Member of the Legislative Assembly). It's a page for one of my province's cabinet ministers. If someone there wants me to take them seriously, they should not post word salads. I am aware that there are some for whom English is not their first language. But the woman I'm talking about doesn't have that issue.
You are, in essence, in your complaint about a person's writing on a Facebook page (which you're happy to use a contraction for), complaining about the digital equivalent of an accent (or maybe dialect would be more accurate). Why? What's the point? Are you advancing the English language in any meaningful way?
If anyone happens to read it who might actually want to improve their writing skills, that's a plus.
Word salads are not "accents" or "dialects." They're word salads.
How a person types in an informal setting has no bearing on neither their literacy or handwriting skills. Your correlation of the two is a poor one.
Where did I say anything about handwriting skills in my posts here?
30 years ago you would not generally have read most peoples writing. You may have had letters from people, but that would be a fairly self selecting group. Nowadays everyone writes on the internet, and some of it is bad.
If 'u' gets the message across, what is wrong with it?
It doesn't get the message across in any meaningful way with me. The first thing that pops into my head when I see it is not "you". It's "that person is lazy."
And you think this is worse than how it was before... why? For a significant period of time, literacy was a function of privilege. Still is, really. If you are learned and surrounded by learned people, of course you will believe that being learned is the norm, and that the rest are knuckle-draggers. But in reality, literacy has never been more accessible than it is now, and despite that, advanced literacy is still a skill that is inaccessible to most. I've interacted with enough people across the spectrum of age to know that "inability to piece together eloquent sentences" is not somehow unique to the youths. Even today, nearly half of the adult population in Canada rank below high school levels for literacy skills.
I said nothing about "eloquent sentences." Eloquence is nice, but coherence is more useful.
You have the privilege of being able to write well, but fail to recognize that you are the exception and not the rule. You're applying a standard that less than 20% of the adult population can reach.
Part of the problem is that many of the basic skills are no longer taught in schools, or are taught inadequately.
It should be interesting to see if more kids are interested in reading due to staying home with parents who might have extra time to spend with them, and using part of that time for reading.
I freely admit that I was lucky to have two grandparents and two parents who were all readers, they all were willing to read
to me, and didn't bother waiting until I was in school to get me started on reading for myself. Most kids have a teddy bear in bed with them. I had teddy bears and a stack of books.
u is perfectly acceptable slang for you. Your not liking it isn't relevant to its ability to communicate.
Obviously it is not perfectly acceptable slang for me. I've already stated that.
