Fuck youtube niches, you should be a youtube personality instead. You could play a steve urkel type character. It would be fitting. Get some oversized glasses, bowtie, pants up to your nipples, take some helium to raise your voice. Keep people guessing about your gender. Perform with a dildo up your ass even
Or figure out some "template" that you can customize in a minute or less that's worth $5 to people. Anything from a mobile app, graphic, testimonial, etc.
