I disagree. If you stream the same thing every day for even just a couple hours you can pretty easily reach at least 100.

I tried a "365 day challenge" or whatever it was called, where you're supposed to stream every single day for at least two hours or it doesn't count. I stopped at I think 14 or something because classes started back up and I didn't want to lose focus on school. By that time I had about 70 followers. You only have to be interesting once to get a follower. Most people don't unfollow, they'll just stop clicking your stream if anything.

If I were to recommend anything for anyone that wants to start out and get big, just pick a game, get good at it, don't play anything else, and stream every day with a set schedule. I almost guarantee if I were to actually have streamed all 365 days I could have been a least considerably more popular than I am now, and if I was playing the same game every day for a year I do guarantee I would be at the very least well above average at it enough for people to stop by and see what I'm doing.
