@wjmaggos @lislegaard @alisynthesis It is possible to subscribe to PeerTube channels on some alternative apps, such as NewPipe.
Another thing you can do is follow them right here. Which has the advantage that you can like, comment, and share the videos for others to potential follow here too.
Example: @potterybyosa is a channel on the PeerTube instance MakerTube. Which you can see in the name.
