Mastodon Data

Data Overview

Tracked instances

For the first two days I scraped the active instances from the list at the tootsuite/mastodon repo, but since it doesn’t update regularly because that requires merging pull requests, I switched to the list over at Please add your instance to this list if you don’t find it on here.

As of 2017-04-19, I’m manually setting the user count of to 1, because apparently there’s trickery going on there.
In the long run, we should figure out how we handle user number reporting, and if that’s something we should even care about.

This is just a quick demo proof of concept by @jemus42 / @jemus42 on birdsite.
This is still a work in progress and there’s a lot to be done.

The site is built in Rmarkdown, using the readthedown theme from juba/rmdformats.

The code for this project is on GitHub.
