See the doc linked in the quick take for our thinking on this. These are the main reasons from there (ones below number 3 are not that important imo), upon reflection I would now swap 2 and 3 in terms of importance:
You can browse past editions with a much nicer + more familiar UI. I would guess this would convert a lot more people per impression than a signup box with no context
We want to start crossing over with substack in various other ways (getting authors from there to crosspost on the forum), so it would be useful for us (Toby) to become more familiar with how the platform works, particularly in terms of social dynamics rather than features per se. E.g. I don’t really understand whether most people discover newsletters on substack itself vs being linked from elsewhere
Substack has a good recommendations algorithm, which will hopefully recommend people other EA relevant content (this feels complementary with the thing above, where it’s facilitating some cross-flow of users between our owned channels and substack)
