Just a nod

2026-02-11T00:00:00Z

Last month I added a new feature to the bottom of almost all pages on this site: a “nod” button. It’s a bit like the upvote buttons you see on bear blog posts, or the ubiquitous like button you get on social media, with one key difference: it doesn’t track or count anything. Before I get into the whys and hows, this is what it currently looks like:

The nod button in all its glory. If you want a clickable version you’ll need to scroll a bit more.

So why bother? I like hearing from people who have looked at my website. I have a contact form that’s also embedded at the bottom of all my blog posts; it’s always a delight when people reach out. Actually writing a message is a pretty high bar that most visitors won’t clear, though. A like/upvote/whatever-you-want-to-call-it is a much less demanding interaction.

And why no counting? I’d been thinking about some kind of upvote button for a while, and counting was always the thing that put me off. Having a number attached to a post like that feels like I’d end up invoking Goodhart’s law and start aiming for a certain number of upvotes or likes or whatever. I don’t want to be anxiously watching numbers, or feel pressured to make a post “good enough” (I already self-filter too much…).

As for not tracking people, that feels like table stakes to me: I’m an individual concerned about privacy, not a giant mega-corporation who wants to slurp up all the data to serve ads or engagement bait feeds. I don’t really need to know someone’s identity to receive a message from them. In the olden days of the internet, you just knew everyone by screen names which could change on a whim and didn’t reveal anything about the real you. On the internet, nobody knows you’re a dog, as Peter Steiner said.

All these constraints felt insurmountable for a while. I considered just making a button that sent a contact form submission with a pre-filled message, but those end up in my e-mail inbox. I don’t really want to have to process them, especially if there’s a big traffic spike like when Hacker News notices one of my posts. I could store the button presses in a database, but then how would I actually know they happened, especially if I didn’t want to watch a number go up?

An Amazon Dash button

So I did what I usually do with these types of problems: ignored it for a bit. The idea rattles around at the back of my head, and sometimes I’ll come up with an answer. I’ve seen this called diffuse thinking. Eventually the idea bounced to the forefront of my head while I was looking at my IRC client, and the solution suddenly clicked. If you’ve not heard of it, IRC is a chat protocol that’s almost as old as I am. Daniel Stenberg has compiled a nice history of IRC that I won’t repeat here. I use IRC to stay in touch with friends, hang around the channels for some open source projects, and I also run a private server with just me and some notification bots.

The notifications I have on IRC are all “transient”: they’re handy to see in the moment, but it doesn’t matter if I miss them. I have some high-volume news feeds, log messages from some self-hosted services, details about git commits, and so on. Basically just background noise of things that are happening that don’t need action. Perfect for the kind of interaction I want!

Now that I’d finally figured out that the transient-notification-shape goes in the transient-notification-hole, I just needed to actually implement it. As part of that private IRC setup I already have a bot that accepts messages over HTTP and sends them to a channel, so the backend was pretty simple. For the frontend I was imagining something like the ill-fated Amazon Dash buttons. My first attempt was… underwhelming:

Flat UIs are in right now, right?… Right?

I guess I shouldn’t give up the day job to become a graphic designer. Fortunately, I came across this codepen from Thierry Michel with some very fun skeuomorphic arcade buttons. I spent some time and LLM tokens on converting the SCSS to CSS, changing the colour, and making a few other tweaks. I really love how this looks and feels.

This is what it looks like in my IRC client when someone nods (and when containers get pushed to the GitHub Container Registry for my projects…):

Receiving some nods on IRC via a bot

When I added the button I wasn’t sure if I’d keep it, but I’ve very much enjoyed seeing the “nods” come in every now and then. I’ve been surprised by how many come in for the various snippets and other non-blog pages on the site. It’s a nice reminder that people are out there browsing the site, without all the baggage of monitoring analytics or tracking likes.
