are there services out there which curate the channels available to insure quality and content? Say if I wanted to follow a particular sport or team, are there services which can set it up? Same goes for any subject
I guess you can find other people's lists and follow them? E.g. a sports journalist's sports lists etc. I have not tried to do that so not sure if there are hurdles to overcome. And maybe someone can aggregate these public lists for others to find/follow?
It's called ESPN.
