 * This isn't generally seen as robust as using Bridgy with webmentions enabled, but some users may prefer it depending on their needs.
 * Ties in nicely with IndieWeb Taxonomy Plugin (as of SNAP version 3.4.10):
 * POSSE reply support: when you add a tweet URL into the response field for a post, when sharing to twitter, it will share AS a reply. Keeping the conversation stream instead of creating a lone tweet. [added by david peach]
 * One thing I will also send to the makers of SNAP is to only send as a reply if both the response URL has a tweet URL AS WELL AS the 'reply' kind being chosen.
