Another thing to append to what uber has said. Not only is good quality content key, but also searchable content even more so. The reason I mention it is that I tend towards higher production value content, high fidelity, high audio quality etc. However, my best stuff is topical news and the fact of the matter is that people don't search YouTube for topical news, they revert to their known good YouTubers. This makes that type of content very difficult to rank for and general game reddits like /r/gaming and /r/games don't react well to self promotion in the same way that the league and GTA reddits do.
