The recurring excuse for the investment is "look at the engagement". Toilets have incredible engagement as well - billions of people use them multiple times per day - but we don't put millions of investment dollars into them. Well, maybe the people investing in Yo do, but most people don't.

The toilet is probably a bad comparison. Smart people are putting millions of dollars into improving them.

Yes, and if you showed me impressive engagement and virality metrics for a toilet that had network effects and a plausible recurring revenue stream (ads), then I would definitely invest (of course no such toilet product exists - toilets don't have strong network effects and don't have a plausible recurring revenue stream in the form of ads).

Toilets: the only technology sector where there's a direct correlation between "input sanitization" and "virality metrics..."
