Not exactly sure what Colin Devroe means when he says he's "just going to publish her on my blog". I guess that means he's not interested in people, like me, publishing our comments on our blogs. Of course there's no compulsion to POSSE to be part of the #indieweb, and if you don't want to, you shouldn't. But I hope he'll still accept webmentions.
On the contrary, I'd much prefer people publish on their blogs in response to my posts rather than on social media. Which is why I do not plan to continue to POSSE. If people find my posts or subscribe to my blog great. If they don't, that's ok with me too.
I'll agree with Jeremy that you don't need to syndicate content or even backfeed to be a part of the Indieweb. Particularly when you're already doing the primary tenets: own your domain, own your data, publish on your own site. (Ideally this is what everyone should be doing in conjunction with webmentions and then all the social networks would be superfluous.
Exactly. If I publish here and people link to it in response, I don't need any social networks.
So, I'm going to support webmention. Not just accepting them and sending them (as I do now), but displaying them also. I need to find a little time to do that since web mentions generally look terrible by default but when I do I'll report back.
Thanks to Jeremy and Chris for chiming in.
