I'm also more in favor of #reposts being human readable and writable. A client might implement a bottom that posts something simple like: <a href="?search=repost" class="tag">#repost</a> Look at this cool stuff, because bla bla [alt](url)

This will then make it possible to also "repost" stuff from other platforms/protocols.

The reader part of a client, can then render a preview of the link, which we talked about would be a nice (optional) feature to have in yarnd.
