I already complained about post on reddit. It says that link to RSS is hidden, which is not true IMHO.

YouTube page contains HTML link to RSS feed in channel page, and most RSS clients should just pick it up just fine.

By the way I maintain a list of feeds, many of them are youtube in link below, so if you would like to find a channel you can use it

Links:
