Symph
I'm a dude with a face and I know how to use it.
I would stop only if those subscribers wouldn't watch the videos. If they kept watching i'd keep uploading just bringing a little entertainment to some people is good enough for me. I didn't do YouTube to get popular, I did it so that I could bring a smile to someone's face,or to make them laugh.
Well at the point I'm at I have about 200 people who like to see my videos and sometimes only 100 of them watch and sometimes as many as 300 do (this is my subs I'm talking about not outside viewers) they also love to comment on my videos and and I like to make them laugh in the comments. So I'd never just abandon all them cause it's not gonna grow, if they keep watching I'll keep entertaining them. I just wouldn't fret over having a schedule or trying to make my videos "palatable for the masses" I'd just upload what I felt like when I felt like it.
I mean come on, everyone wants to see some evolution in the things they do, like they know they are doing the right thing.
