Actually it does matter what I think, since I am user of language and, unlike many others, I actually care.
When it comes to using, spreading and understanding language, every single human being matters, because every single human being acts as a multiplier.
What also matters, is that there are far too many people who are, despite having graduated schools, barely able to read written words.
These are the very same people who also want to convince everybody else that it does not matter.
