How about: write it on your website and tweet a link to it.
Also I’m skeptical about the engagement that people think they get with Twitter. It may appear that more people are seeing your output, but they may not be actually reading or thinking about it. They won’t refer to it in one of their own articles two years from now.
What do you really want? Twenty clicks of the heart button? Or one person actually building on your ideas?
I think for your claim about what Twitter's good for to have much meaning we'd have to define "tweets" and what you dislike about them. Are you saying the whole idea of breaking a long writing into smaller pieces is out? Do you just dislike the UI? Do you dislike people being able to comment on each piece independently?
