Mastodon is perfectly usable for microblogging, and, moreover, it's currently the best usecase for the tool. You can't find partners for conversation as easily as with established platforms with network effects, but you can use it to publish. With Mastodon, you can quickly create account you can send notes, links or images into. This account lives on the open web without registration required. You get Atom feed you can use to re-display the content in any way you want at other sites, or to share the content with people who don't use ActivityPub yet. You get "comments" for free for users willing to get ActivityPub account.
