I'm sorry i haven't been around much hey been really studying for upcoming exam tomorrow :/ i hate exams but yeah i agree with all of you for the like and comment part... a lot of my videos i try and involve those that watch by asking themk questions and so on and i get 2 views 3 views and such I feel that sometimes its not worth it but i push on anyways for a hope that someone stumbles in and says "hmm... this is good let me tell my friends" and then it starts rising in popularity and such though i think you need to push forward and be stubborn and keep uploading them
