Possibly a generation thing - I think in 10/20 years people will start to view vlogging a little differently, it will possibly be seen as an achievement because that’s the medium of the day so having a back catalogue of content will be rich pickings, especially for those who stick with it. But it’s not seen as credible and lasting by today’s standards where people view literature and writing as a sign of accomplishment (it’s so difficult to be published that you admire either the creativity for a story or the intelligence to have something published).
It’s rare to get success the Fifty Shades of Grey route, self-publishing to being bought out, but if you have enough money to gamble you can create something that’s polished enough to look like the real thing. So he’s investing in wanting to feel credible, you can see that in all of his reactions, and that is admittedly something that makes me feel bad for him. He’s creating something that his fans will buy just because they’ve followed him for years - no different to a Sophie and Dave ‘Chip pin’ or a Lodge Guys sticker, this one being a diversion because even Sophie doesn’t want to be known as a master pin maker, she just wants money, and there’s at least something admirable about that.
Adam already has the Patreon etc but feels - clearly - that emptiness that his pal Gary could never feel, he needs a sense of achievement in the way most of us do. His attempts at a guide book and a children’s book prove that, this is just a natural step.
If he was a little more self-aware to the extent that he could be objective enough to see what he was doing, because there’s a difference again between playing at being a writer and knowing that you’re doing it to just exploit, then I think he could very well get a decent job in social media and marketing. The difference with him is that he still lingers on the Gary side of the divide of not being self-aware *enough*, that he thinks that the things he buys are the things he does. That writing somewhere between 50,000 and 100,000 words makes him an author.
