Syndicating blog posts with Feed WordPress is a good tune, an old song here, from the heady days of early ds106 to my current class.

But what about aggregating comments from multiple blogs? It’s come up often over the years, and recently in the Twitters by fellow RSS junkies

What Martha built is rather useful, check out the dropdown menus for seeing comment counts.

And yes, Tom was right, I built a comment reader for the original Thought Vectors course (the URL is DOA, pointing to WPengine??) based on the knowledge that all WordPress and Blogger blogs provide an RSS feed for comments.

Yup this blog, yours (if WP or blogger) has a comment RSS feed. It’s predictable for WordPress- take the blog URL and tack on /comments/feed or

However, I’ve grown less sure that a separate comment aggregator site is the best way to go. It’s still wieldy to view, and keep track of what you read. Already an RSS reader is best for reading a lot of blogs; I have always down the same for my students blogs AND comment feeds.

In a glance I can see how active the comments are on the entire space, or one blog.

Scanning the comment activity on my netnarr student blogs.

This is done with some custom coding I put in all my syndication projects, this on the page where I list blogs within a sub category for my class among all the aggregated blogs

The Blog Comment OPML link dynamically downloads an OPML file that contains all subscriptions for blogs that have comment feeds (meaning WordPress and Blogger blogs). The URL can also be used in Inoreader for a dynamic subscription (loving Inoreader more on a daily basis).

I have done this for all my classes over the years teaching syndicated courses; it’s much easier for me to know what posts and comments activity are, and the web site, while pretty is not an efficient way to eyeball the activity.

How’s it done? Well, I harness long term wishes to wrap a lot of my Feed WordPress code into a plugin, but for now it’s still spun up by me. I recently set this up for the Ontario Extend syndication hub (I am also available for syndicated wedding and bar mitzvah sites) (bad joke).

As is two bits are needed in the themes functions.php — this is lazy, but I use a PHP constant to keep track of the default category ID

And we also have to set up parameters can can pass in URLs

To put things in motion, create a blank WordPress Page named Comments OPML. By default it should use these template to do stuff.

Just calling it without parameters withh generate an OMPL for all blog comment feeds while passing a parameter like generates OPML comment feed for my class while will fetch the comment feed from open participants.

Yes RSS readers are archaic, eh? But to me it is a more manage way to scan the comment activity than a punch of post-like things.

But more than that, I like to introduce my students to using feed readers. I did this last semester for my seminar students (with 4 students I just had them add the RSS directly to feedly) while at the same time encouraging them to build their own set of feeds.

Got comments on the idea of comment syndication? Yak below.

  1. Hi Alan,
    Looks like OPML is getting some well deserved love at the moment, so getting into a reader via opml would be excellent. FWIW inoreader lets you sub to an opml file on the web and adds subscriptions when they are added to the opml.

    The other thing I am thinking is worth a look at in this context is the indieweb and One of the things does is send comments to your blog when someone replies on, and replies to the reply. In this way acts as an aggregator and place to converse. The conversations go back to the original post as webmentions. Of course this means you need to support webmentions on your blog with a plugin (that also lets you comment on someones blog by posting to your blog). I suspect that this is not ready for a class full of folk with differing abilities yet but it is quite fascinating.

    1. Yes, that subscription OPML in Inoreader is super handy for the way I do my OPML scripts as dynamic. In fact I got myself confused because I kept deleting subscriptions to my 2016 students blog comments in Inoreader, and they kept returning… until I remembered that is was dynamic link.

      That is an interesting approach for dealing with dispersed comments, I guess I should catch up to you in the thing… my hunch is that it’s a bit more for new folks.

      I miss crossing paths with you!

      1. Hi Alan,
        Webmentions don’t really need, supported by WordPress with plugins & themes. Sort of like modern pingbacks/trackbacks. Would be interesting in combo with an aggregated community (which is but so is a FeedWordPress site), but need a bit of determination from bloggers at the moment.

        Our paths may not be crossing but through the wonders of RSS I am following yours;-)

  2. Hi Alan,
    I’ve been trying to work through this list:

    and evaluate which of these can be realistically self-hosted on a faculty/student DoOO. I have miniflux running on my domain, but it isn’t the solution I’m looking for mostly because of it’s newest version moving to the ‘go’ programming language, and also its lack of an option for a public view of aggregated sites and posts (everything is behind a private username and password). I hold on to my belief that there is a great tool out there that could eventually be worked into Installatron, but I’m still seeking.

    I agree 100% about modeling the practice of building feeds for learners. I’m starting to think personal aggregation is the answer for individuals, and course aggregation through Feed WordPress, WPeMatico, and other plugins is an answer for curation, or assessment, or discovery by the public. There are many great reasons to pull a community’s or a class’s posts into a hub WordPress site, but I think really building a practice of engagement is better done via a personal feed aggregator.

    Thanks for writing about RSS.

    1. Thanks Tim, your input means a lot.

      Still I am not 100% convinced of the need for reclaiming or having a hosted aggregator but do like the notion of people seeing it as a personal tool for their own use. The most important thing to have is your subscriptions as an OPML file. But then again, if it’s a reader that stores content, that’s a reason (thus Feed WordPress is more than a reader, it’s an archiver).

      At least there’s much to choose from!
