Big validation for Substack and the author investment model.
So I'm not sure how substack being full of low-quality SEO content hurts me.
I've subscribed to multiple Substack newsletters because content creators I already liked moved or launched new projects on Substack.
Obviously everyone is different, but my impression is that Medium was trying to sell the "Medium brand", and struggled because a lot of people didn't find the "Medium brand" worth $5/month. Conversely, Substack is a platform for people to sell their own brands, and a lot of people find those brands to be worth $5 (or $8, or even $10 in some cases) per month.
Will people now subscribed to slowboring.com suddenly stop in significant numbers because there's another blog/newsletter built on the same platform somewhere which is really low quality? How would they learn this, and having done so, why would they care? In another comment, you say:
> [LCD blogspam] will devalue anything published solely on Substack
I don't value anything now because it's published on Substack. How can you devalue zero? :)
Substack seems to be trying a model where they will, in some cases, guarantee an author will receive a minimum amount of subscriptions for the first year, in exchange for a hefty cut of subscription revenue. I don't think we have information on how the program is doing on net, but in at least some high profile cases they've turned a profit on it. Also, even if the program is significantly loss making, it should be easy enough to shift to profitability; just scale down offering new contracts to people without large existing readerships.
The model is not enormously different at the twenty thousand feet level, but I think it has the potential to play out quite differently in practice nonetheless.
Yeah Substack's server costs are probably fairly low, so they could also probably lay off some engineers and coast for a while before a competitor gobbled up the market.
I never understood why Medium tried to be the Netflix for words. To me it always made more sense for them to follow Vimeo's model (disclaimer – I work for Vimeo): create tools that paying customers use to help them showcase their work, tools that let them customise how it appears, and tools that let them monetise that content.
