Well you can comment on someone's last post, but I see what you mean. It ought to be possible to create a sort of non-private messaging facility. We have private messages via transfer memos, but that is not much used. It's a matter of someone building it into the front ends. I've not looked at the new Dapplr mobile app that seems to encourage micro-blogs.

I'm not saying Hive can be everything to all people, but it's an option that most people could make some use of. You don't have to write posts if there is content you like to just follow and comment/vote on. From what I know it offers more than Wordpress and plenty of people use that. It will never be Facebook or Twitter, unless it gets some radical changes, but does it have to do all those do? I don't see people writing long blogs on Facebook.
