I’m experimenting with Webmentions and Semantic Linkbacks, at Chris Aldrich’s suggestion. Theoretically, if you reply to this post on micro.blog, the reply will aggregate to kfitz.info. Assuming I have things properly configured, which is no small assumption.
@kfitz Hooray! Looks like you've got it up and running. Keep in mind that you can allow comments but moderate them all before they appear on your site.
Keep in mind that in addition to comments coming back from micro.blog, you'll also be able to receive reactions from other stand-alone websites that send webmentions.
