I like to think it works to meet the needs of both groups of people. It's also why I tend to group all my hashtags at the end of a post. So they don't have to listen to "hashtag this, hashtag that" while they're trying to read the post. If they don't care about hashtags, they can skip, and not miss anything from the content.
I've learned a LOT just by "listening" to conversations about accessibility on here!
