Scott Hanselman states he stopped because he was tired, not that he's switched mediums. The Tiktok / YT comment was a joke; he still does lots of media for his job though.

If you are serious about communicating then you MUST blog in addition to tweet. Twitter is for soundbites, not lengthy articles. You can't expect people to read tweet after tweet when they would rather read a long continuous article.

The dude probably has the software that breaks down lengthy articles and tweets them in reverse order but that shouldn't be abused.

And what happens when you fall foul of twitter's rules and get banned?

Not sure why you were downvoted, as those are valid points. Twitter is the best medium when it comes to talking about subjects in depth. It is good when it comes to making a quick hot take, but not in depth articles or explanations.

Unfortunately, a lot of people don't engage much in long form discussion as much as they would a tweet. Tweets are much easier to discover, find, and view compared to a blog post. It's much easier to click like on a tweet or retweet something, and bigger engagement numbers == better. So people instead will write out tweets instead of blog posts. I don't care for it much myself, but such is the modern internet I guess.
