Blog is historical something?

ハローキティめっちゃ可愛いよねわかる♥

I think that blog is historical something and I should use Twitter in this 令和 period so I didn't(haven't?) use such service.
However it was wrong. I knew a lot of youth also use blog service. I don't know about overseas.

In Japan 99% of youngster use twitter and instagram(this is from my view), but how many youngsters in your country use blog are there?
