I just launched my Excel add-in on Hacker News:
Fortunately my timezone means I now get to go to sleep instead of compulsively hitting the refresh button all day long. :D
I am following a strategy of scheduling posts on different sites, Slack chats, and email lists, with the two main ones being Hacker News and then Product Hunt.
For HN I wrote a post (linked above) about how I built the add-in using web tech, which I hope will be valuable to readers there.
I'm hoping this scheduled approach will mean better traction than previous things I have launched.
Tomorrow is Product Hunt.
Will report back!
