The summary of the general agreed upon direction is this: When a content aggregator (in this instance micro.blog) creates a syndication post of your post, if it uses Microformats, it should mark your post with h-entry and u-url or u-uid. If it doesn't use Microformats then it should at least mark your url up with rel=canonical (this is following the first two steps of the Original Post Discovery algorithm).

micro.blog should then send a webmention with the syndicated copy as the source and the original post as the target.

Because this isn't a common pattern yet, it is recommended that micro.blog puts this option behind an opt-in mechanism since many webmention endpoints would just treat this as a "mention" rather than as a "syndication notification". However for those that have updated their webmentions to look for syndication notifications, if they could enable these, it would really help begin to streamline some of the cross-site replies. While this wouldn't negate the need for https://github.com/microdotblog/issues/issues/75 it would help to curb some of the issues around it, while the ultimate solution for Cross-site replies is determined.

Any new discoveries in Slack/IRC will be posted here, but there was a pretty open general consensus on this. If there are no updates in the next several days it should be considered good to move ahead on.
