If I correctly understand the development trends of the web, then in the future the mass of content generated by users will somehow be streamlined and filtered so that only high-quality content remains. I think that this is a chance of the Internet to return to a good Russian language. Agree that the fall in the general level of literacy on the Internet reaches its maximum and inevitably affects the younger generation, who simply do not understand why bother spelling, because everything is clear.
I often feel genuine delight when I read a book published in the middle of the last century. The eye will never stumble on typos and incorrect punctuation! On the contrary, reading a really good text, I myself am learning the Russian language. It would be great if the Internet has become such a source of high-quality Russian-language texts, because it will influence the minds of our children. ')
And how to implement it - the army of editors or software is a matter of technology. The main desire.
UPD Friends, you convinced me of the naivety of my idea. Really treating the symptoms is pointless. Education and education - this is where the dog is buried. And plugins for browsers can and should be done - for perfectionists)
