Ok, this is kind of a larger question with sub-parts. Y’all may have noticed I keep asking about stuff related to Twitter integration. I added FOAF markup to my XHTML 1.1 (strict) blog what seems like fifteen years ago, so I’m no stranger to the semantic web, but I kinda gave up for a while and just used Twitter for the social for over a decade now.
Is there any native support for adding an external URL to a post? I believe I can make the post a “link post” (ala Daring Fireball) through a custom theme, but is the URL stored in the backend as a “this is the external url for this post” or as “this is a field added by a custom theme”?
Is the Twitter cross-post code capable to tell their API “retweet this URL/tweet id” given appropriate input via modified RSS or something? If not currently, would this be a possible feature or more like just too much?
