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
That would be very subjective. But probably exists.
I am a heavy user of Twitter's List feature, and have columns in Tweetdeck for friends, local, sports, politics, colleagues etc. And try to curate these for my interest as best as possible, ie weed out too noisy tweeters etc.
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?
ESPN only really cover one country. If you're in the US I'm sure it's fine but for everyone else the coverage is not only almost nonexistent but often factually wrong when it does exist. I saw AFL coverage on ESPN where they did not understand the distinction between goals and points and left the wrong scores up for ages.
