@springdew I'd drop a note to email@example.com so Manton can have a look. or there may be some helpful WP users in the Micro.blog community who can offer tips.
If you don't use Micro.blog for hosting, it isn't technically cross-posting, because you are only posting to your WP blog, and pulling your WP posts via RSS. As far as I understand it anyway...I dabbled in WP-hosted in the early days, but I found it to be more tech than I wanted creating friction, and went to M.b only. But lots of folks here are on a basic account and connect it to their WP-hosted blogs.
