Nobody’s going to like to hear this but … Nextdoor. Especially if it’s a B2C app, ND is your best source for early testers and users. Source: got my first paid users for my first ever iOS app this way thanks to 200 waitlisted neighbors. It works.
My little nights/weekend project: 13 days from hyperlocal social validation on Nextdoor to live on App Store, this is my first-ever iOS app. And I absurdly, embarrassingly underestimated how complex/non-trivial this problem is.
Forget the bathroom doors; can we at least bring back proper shower stall design that uses full-length doors instead of the 1/3-length piece of glass? More glaringly, those of you who know the Hilton MUC for instance, it's utterly mind blowing what they've done: the shower stall floor is on the same plane as the rest of the bathroom floor -- i.e., it's not sunken at all -- and it's not sloped or otherwise angled, either, to prevent water from seeping under the door and flood the whole floor. And this isn't like one-off bug in one room: we've stayed their countless times, in different rooms, and every single one suffers this problem.
RIP Jane Goodall. Not to make a flippant pun but, thank you indeed for all the good you brought to all of us. By discovering humanity in our chimpanzee cousins, you helped us see the humanity in each other.
