Welcome, Facebook and Twitter - Seriously - Substack co-founder Hamish McKenzie looks back at how he reacted to the announcement that Facebook and Twitter are getting into newsletters - I like that he’s writing publicly about it, still feels a bit awkward, especially finishing with the “we’re looking at you too” bit, but real life is awkward sometimes, I guess it’s genuine, as a Substack user my hope is that they announce some form of API soon, later today I’ll be preparing tomorrow’s newsletter, which will take several hours of copy paste, when with a bit of automation I could concentrate just on the writing part, anyhow I still like Substackblog.substack.com #
