My guilty pleasure is Cruising Alba ... very bohemian!
Very few will be making any money and those that do will be struggling to come up with new topics - there's only so many times you can film the same bit of canal, except maybe in different seasons? I predict an increase in click bait headlines followed by very so so videos unless they come up with a fresh angle on it - not sure what that could be - what would people find interesting and viewable?
I'd personally like more engineering videos and trips into the engine bay generally, but I know I'm a bit odd like that.... its my favourite room on our boat!
