(This is before other, more basic criticisms of Substack, like that it seems to have really only had success with a small group of bloggers who I would pay money not to be exposed to.)
Substack announced "Substack Notes", which is obviously a Twitter clone. Then, Twitter has disabled likes and retweets of _ANY_ post mentioning "substack". Today: we are seeing the lines form of the Substack supporters vs Twitter supporters.
Its no longer possible to host a blog on Substack and post links to that blog on Twitter. (Well... its "possible", but your links ain't gonna attract a lot of traffic without retweets or likes, so more like its pointless) So the bloggers using Substack are forced to choose.
