Replied to an annotation on Connections by Kathleen Fitzpatrick by Heather Staines (Hypothesis)

Social media networks provided immediate solutions to a few problems with those early blogging networks: they relieved the moderately heavy lift in getting started and they created the possibility of connections that were immediate, dense, and growing. But as those networks expanded, they both pulled authors away from their own domains — so much quicker to tweet than to blog, and with a much speedier potential response — and they privatized and scattered conversations.  

Exactly the use case that annotation is hoping to solve! Enabling the connection between different sites.

While I’m pondering on this, I can’t help but feel like your annotation here is somewhat meant as a reply to Kathleen. I’m left searching to see if you tweeted it with an @mention to notify her. Otherwise, your annotation seems like a cry into the void, which I’ve happened to come across.
I say this because I know that her website now supports sending and receiving Webmentions (she notes as much and references a recent article I wrote on the topic within her text.) If Hypothes.is supported sending Webmentions (a W3C recommendation) for highlights and other annotations on the page they occurred on, then the author of the post would get a notification and could potentially show it on the site (as an inline annotation) or in their comment section, which might also in turn encourage others to open up the annotation layer to do the same. Hypothesis could then not only be an annotation system, but also serve as an ad hoc commenting/conversation tool as well.
You may notice in her comment section that there are 60+ reactions/comments on her site. One or two are done within her native comment interface, and one directly from my website, but the majority are comments, likes, reshares, and mentions which are coming from Twitter by webmention. Imagine if many of them were coming from Hypothesis instead… (try clicking on one of the “@ twitter.com” links following one of the commenter’s avatars and names. What if some of those links looked like:

instead?
