Twitter is absolutely the worst thing to happen to the internet. Low effort, inherently self-aggrandizing and standoffish, literally impossible to express a complex or nuanced thought. The only people I know who regularly engage with Twitter are extreme narcissists and conformist thinkers, and yet all of Twitter considers themselves to be the Important People. This mentality has crept into all spheres of public life.
Good blogging requires effort, effective communication and something interesting and original to say. Those days are long gone.
