I was watching Christopher try to decide which mastodon instance to join. This made me realise that we need a way to preview instances’ local and federated streams. So I made one: Here's mastodon.social and here's toot.cafe
How this works is that from mastodon 1.1.1 the public timeline json api no longer needs authentication, so I can read it by default. I do this, then use a tempate to render it as an h-feed compliant view.
I also added a list of known instances from instances.mastodon.xyz, though I wasn't able to fetch the list dynamically.
I hope you find a mastodon insatcne community that you like. #indieweb
