@tekphloyd This is something that is already supported on most servers. I think it's only base Mastodon that doesn't expose it, and even goes through the effort of stripping much of the markup when displaying posts.

This is the reason some clients have poor markup support, it's only been tested with basic Mastodon. Posts themselves are HTML, and are rendered fine in most places.

This post has bold and italics as well as a link with description.
