I've got a Twitter account and post my poems (usually via a link) there as well. I haven't found it's an environment conducive to much "intellectual depth" (and hence poetry) ... it's like everyone's on a sugar high and can't take the time to think for 30 seconds. There are exceptions.
I've actually been amazed by the differences in personality of each social media platform. Other than Steemit, I found Instagram was the most receptive to poetry.
Have you had any experience posting poetry outside of Twitter/Steemit?
