Micro.blog proves it's possible to provide a comparable experience--in some ways I prefer it, although that has much more to do with its aesthetics and nascent culture than any underlying technology. At any rate, if your blog is hosted on Mastodon itself, you don't even have to know it's a blog, per se--you can just use it exactly like Twitter.

The catch right now is that Micro.blog is a paid service. I don't see any reason why someone couldn't set up something very similar built on the same tech--other than, of course, the willingness to put in the time and money. :)
