Want to easily embed individual twitter messages in your blog posts? There’s a WordPress plugin for that. Twitter Blackbird Pie adds several options that allow you to embed a nicely-rendered HTML representation of a tweet. It adds buttons to the editor, shortcodes, even oEmbed support.
It uses a variation of the Blackbird Pie tool that Twitter created, but integrates it into WordPress itself.
If you’re using WordPress.com, this functionality is now built-in as well.
