Yay, @katjeskat is up and running off three https://glitch.com projects (in the order in which they should be started):
1. listen to mastadon and push mastadon timeline to a hyperfeed: https://glitch.com/edit/#!/zinc-cardigan
2. archive the hyperfeed: https://glitch.com/edit/#!/crystal-menu
3. subscribe to hyperfeed and reply with 'meow' when I tweet: https://glitch.com/edit/#!/gray-rayon
