Let me tell you about OpenMentions



OpenMentions is a website I made around the idea of OpenTopics, which are targets for WebMentions with a standing invitation to tag them whenever you want. This, I hope, creates a little more discoverability in the WebMention ecosystem.

OpenMentions also supports ActivityPub.

Eh, what, Matt?

This post is about my website, which you can add comments to from your own website.

If your website supports WebMentions (the tech that does all that) and auto-sends mentions, all you need to do is add a link to the topic page (or question of the week). If not, there’s a ping thing where you can post your link on the page you linked to.

WebMentions are a better, more modern Trackback.

Why, though, Matt?

Not long after I started using WebMentions, I started to think thoughts. Dangerous, I know. My thoughts ran something like this:

I remember when Technorati was cool. It used to index blog posts.

I wish we had something like that now, but a bit more IndieWeb.

These WebMention things are great. You could use them to live update blog topics. I wonder why no one has done that yet.

With those thoughts refusing to leave my head, I saw an idea I could make happen. That was when I made OpenMentions. I was, I would later learn, following the IndieWeb principle of make what you need. Closely followed by use what you make.

I tag OpenMentions from many of my blog projects and try to encourage others to do the same. To avoid drowning out less frequent voices, I try not to tag it too much.

Okay, sure. What’s the tech behind OpenMentions, Matt?

Because I lacked the spoons to code something from scratch, I took a few minor shortcuts. I created a WordPress blog, custom-themed it (not my best work) and used the excellent WebMention (and later, ActivityPub) plugins. After all, why reinvent the square wheel?

I wrote a simple plugin to help me add topic pages.

That’s it. Not much at all.

You said something about OpenTopics. What are they, Matt?

OpenTopics is the theory I cooked up first. My idea was that my website should not be the sole endpoint because it could go away.

I envisage a set of meta tags that all topic end points to be found and followed. But, for now, all I do is link from a topic page to other websites that want to host more specific topics.

You silly-billy, Matt. IndieNews is a thing!

I first learned about IndieNews in the last few days from Wojtek Powiertowski’s blog post, “Exploring the Smallweb and IndieWeb“. To be honest, I might not have made OpenMentions if I found IndieNews first.

I think both can coexist because the overlap is only a good thing. I’m about to go add links to IndieNews to OpenMentions.

Who can use OpenMentions?

Anyone at all.

What about spam then?

Because WebMention checks for an inbound link, spam has been entirely self-filtering up to now. Long may that last.

Hey Matt, you broke something. My ping was accepted, but I don’t see my comment.

WordPress holds comments from places it has not seen before for manual approval. I keep meaning to write a plugin that will auto-approve WebMentions and ActivityPub replies. I’ll get there eventually unless someone beats me to it.

I have suggestions, Matt

Every topic page has a topic meta. If you need to be more general, the OpenMentions Mentions page exists. Send a mention ping to whatever chatty meta bit you want to talk about.

Or comment here (even though OpenMentions is where the cool kids are).

In conclusion

In conclusion. I made a thing. It is sort of like a forum, except you use your own website (or Mastodon account). It is free, open to all, and (in my egotistical opinion) rather cool.

I would love more people to use it.

PS

I’m writing this for IndieWeb News and filing this as IndieWeb on OpenMentions. If you read it on MatrixDreams.com, the middle bit has some cool formatting.

Really like how it turned out (after couple fixes)

Inspired by the Now page concept created by @sivers, I've finally published /now on my #PersonalWebsite! https://bm.gy/now

Had to tweak my #StaticSiteGenerator just a bit to accommodate this unique new post type: The latest post will always be displayed in full at /now, with past entries eventually appearing as a simple list right below it.

That was a fun technical exercise as well as a nice excuse to reflect. Highly recommended!

I found it through @fish 's delightful monthly roundup, the Checkup Counter - magic coming through my RSS feed

If you don't have an RSS feed (or a JSONfeed), I probably won't read your blog. I don't like getting newsletters: too much stuff in my inbox already.

Starting work on IndieAuth for Jottit today. Building authorization and token endpoints so people can publish from any Micropub client. Love how the IndieWeb specs are small and focused: each one does one thing well, and they compose beautifully together.

First up: a simple consent screen and some JSON files for tokens. File-based storage makes this remarkably straightforward. #indieweb

so i'd love an open discussion about something that i don't have much vocabulary for, if only because there are so few examples of it on the world wide web. anyone/everyone is welcome to chime in.

back in the mid/late 90s there were some attempts at turning web forums and chat interfaces into virtual worlds. beyond all of the 3d chat rooms and telnet muds, there were some 2d graphical sites like moo.ca. The Canada SchoolNet moo was a mud/moo that allowed users to add/remove/modify rooms in real time, in-browser.

snapshot archived here - click 'Web Walkthrough' to walk around:
https://web.archive.org/web/20010417181313/http://www.moo.ca/home

Furcadia went a hundred steps further and integrated a 2d tile-based world with a world editor *and* script editor, so you could build your own "dreams" (multiplayer instances) within the shared game world. the entire game was built around socialization.

both of the above games are not just fancy web chat terminals. building and decorating the game world is a critical part of the social experience. you create a dining room, put chairs in it, program the chairs to allow players to use the 'sit' command, and then invite people into your dining room for a make-believe dinner party.

we now have reddit and various web forums. they're effectively the same threaded conversation that has been around since the usenet days.

what i *don't* see anymore are graphical WWW virtual worlds built around socialization. we either lock down everything and only allow chat. are there web-based MUDs/MUSHes/MOOs that allow for both world building *and* conversation?
