As for Nebula evolving in to a dating app, if a single person ever shared anything related to this app in a tinder bio for any reason at all, I think that's when I'll know it's time for a hard pivot. I believe (and I could be totally wrong) there have been links to people's odors and who they find attractive because we seek partners with complementary immune systems to our own and one indicator of that is the way someone smells. Maybe sleep patterns have a similar correlation. If the pivot ever happens I'll credit you for giving the idea.
