Popular instances
The table of all the instances I could discover was getting huge and taking an eternity to load so I decided to make a smaller list. It would be nice to have some meaningful measure to use but all I could come up with was number of users so that's what I've used. Maybe in future I'll change this to some measure of activity.
If there is a link on the instance name then it might take you to the instance's local timeline (although it's probably only reliable for Mastodon instances running 4.0 or better). Due to the width of the table it won't display on something that doesn't have much screen real estate.
You should be able to click on the column heading to get the table sorted on that column. Expect weirdness though.
