I've just updated mathstodon.xyz to Mastodon v2.7.1.
Release notes: github.com/tootsuite/mastodon/
There's now a profile directory, which you have to opt in to, at mathstodon.xyz/explore. Not sure it's particularly useful on an instance as small as this, but who knows!

@christianp seems like LaTeX rendering broke though?

@btcprox good spot. Now fixed.

A Mastodon instance for maths people. The kind of people who make $\pi z^2 \times a$ jokes.

Use $ and $ for inline LaTeX, and $ and $ for display mode.
