i'm skeptical of remote work for early-stage startups. i'm not religious about it for larger companies; i think it works for some and doesn't work for others. if it works, great. if it doesn't, that's fine too.
the only thing i felt really strongly about (when yishan explained the challenges they were facing and asked for my advice as a friend and not an investor) was that reddit needed to be super generous to people that were unwilling or unable to move, and i think they have been.
