I think its just that everyone on hacker news likes to pretend they have to scale to the size of google even though most people aren't even in the same ballpark.
It isn’t loading, just sits there spinning. Pile of shit. I wish they’d chosen to write the service as a reliable cgi rather than some web framework where errors are eaten and hidden in Ajax calls.
Uber eats let’s me place the order then vanishes when it comes to paying.
Nandos yesterday told me error UK03 when I tried ordering in the restaurant, slightly better, but perhaps those more concerned with scaling to a million concurrent users could deal with 1000 reliably first.
[1]: an oxymoron, I know
I think it is also worth to mention there are plenty of "slim/light" frameworks that do very little (i.e. take care of threading, provide html request/response as writable streams, have the http headers parsed for you into a Map-like data structure etc.). Those lightweight frameworks exist i.e. express without middleware (nodeJS), Nancy (.NET), Flask (Python) etc. The "full-blown" counterparts would be ASP.NET or Django which bring far more to the table than you might need.
