A red flag for what, though? You have a blog, and people who want to know what you have to say follow it. So you’re doing exactly the “author feed + comments” paradigm that I’m expressing a preference for, yourself, but for whatever reasons you’ve decided not to host the feed (i.e. blog) on Discourse, and to only host the comments.
In fact, there is such a demand for some kind of “feed + comment” solution based on Discourse that an increasing number of sites are going to the trouble of wiring up a Ghost or WP blog to Discourse so that they can at least do the comments half, here. And of course every now and then somebody posts the obvious question in this forum, i.e. “Discourse is a great authoring and publishing solution, so what’s with making me wire it up to an external blog so that I can blog with it? Why doesn’t it have out-of-the-box support for just blogging directly on it?”
So I don’t have to defend the idea that “follow my feed and comment/like/share” would be a popular way to use Discourse, because to the extent that such a thing possible it’s already happening, and people are jumping through hoops to make it happen by mating Discourse to something you can actually host a feed with.
I think it’s not at all a stretch for it to handle both cases. As for if I’m advocating for that, I guess I was, but at this point it’s clear to me that (absent a dedicated social plug-in) it’s not going to happen in any other form than it’s currently happening, i.e. somebody else (Ghost or WP) hosts the feed, and Discourse hosts the comments.
The team here seems dedicated to keeping Discourse squarely in the realm of a Google Groups and/or Disqus replacement, which is still awesome because both those things suck and should definitely be replaced by FOSS.
My take-home from this thread is that anyone who wants to see Discourse host a followable feed directly should focus their efforts on a plugin, so that’s what I plan to do. Right now, I’ve started hacking at my own, but I’m more than happy to ditch that and contribute to a more mature plugin that’s headed in that direction.
