Thank you for all the great tips. I was thinking that one needs to be both persistent and patient, now your thread proves it. As for the niche, I think I have already found mine. For now I am focusing on chatroulette but I am going to start making real life pranks as well once the subs start piling up. I am not sure what people are going to like the most but I am trying to be get to know my audience, as small as it is right now, on all of my social networks, in order to fine tune my niche.
The videos I have made so far seem to have gone out nicely, people started contacting me with all sorts of opinions but I think that time and more videos are going to fine tune my channel. My original idea was to upload two videos per week but I think that I will switch to three videos per week pretty soon.
Thanks a lot for this awesome post, it's really informative and kind of gave me some confidence. Keep up the good work!
