Edge YouTube Creators, what makes them work and what are you watching?

Out of the dozens and dozens of youtube gambling creators/streamers I find myself tuning into this one everyday as well as other very specific creators in travel, tech, etc. What is it that makes these stick to us? I really can't find a thread that ties my ten or so daily watches and my twenty or so weekly streamers together. What draws you in for the long term? Can these creators survive or are tey a flash in the pan?
