Makes sense, and you are 100% right that people will watch what they like and maybe pass on stuff that interest them less. It's the same as most forms of media, I don't quit reading a newspaper jut because one article on the page doesn't interest me.
I do like the one take vlog format, it's very spontaneous. LOL! "I like food", can we expect "cooking with Lamarr" or restaurant review/vlogs? ;)
