You used the words “abuse” 31 times and “twitter” 12 times in the article. I googled for “twitter abuse” and you got on the first page, congratz :)
Joking aside, I have to say that I don’t agree with you. Perhaps Twitter will be dead in time, but not because of being an “abuse” platform. Yes, Twitter has a strong political side and it has lots of abusers (as much as the others), but also it gives us some functions to prevent them (unfollow, block, report, etc.).
Besides, these problems are not limited to Twitter, so we should talk about “humanity” in general.
