[Mr. Maggot]

If you really want your videos/streams to go somewhere(as in gain some popularity), I don't think these are the right forums to spend your time on. Even if a couple of people say they are interested in your videos. They will at most only watch a few of them and more importantly will not be able to provide valid and specific feedback for improvement.

I'm not trying to put you down, but since you mentioned "spread the word". Posting in reddit/ specific forums for such things might actually get you closer to your goal.

If these topics are just for conversation, by all means go ahead.
