> Right now, I could make a comment on either your first or second paragraph, or on your entire comment. However, there is no way to determine which category my reply falls into until you have read it entirely. On a platform like Twitter, where there can be up to 100,000 comments on a given piece of content, this is very useful.

Oh, look, I have managed to reply to your second paragraph without having to use twatter, how quaint!
