I think that Matt has kind of fallen into the ‘YouTube-creating-for-a-living’ trap. His channel started with high frequency, but widely ranging subjects, changing style a lot — clearly with the intent to build up a viable amount of subscriptions, but this has not worked out, I think. He may have tried to emulate Alec Steele, whoÆs channel is very successful.
If and when he reverts to the earlier series-of-a-build, like he did when he was graduating from college, interest probably will pick up. (I liked those better.)
He is in Canada at the moment, doing a course at Veritas’. Hope he perseveres, because there is potential!
