The (new) founder, John, said that the user base isn’t as active as on Slack (though I doubt it is that much higher), and he is rebuilding the project. As far as I understood, the community can make their own bots, but no official ones in Telegram.

I mean it’s his own project, all and all, so I hope someone will make a TG bot at some point.

Again, gladly, WIP has an official bot hehe!
