Fair enough; 100 was sort of arbitrary, but there is some metric when you're sort of at google scale and cutting down on power costs or achieving absolute minimum latencies between datacenters has a meaningful impact on the bottom line. Draw a line somewhere, and yeah, Reddit is probably on the other side.
Reddit has always amazed me with what they can do with extremely limited resources.
But it looks like that attitude has finally caught up with them, especially since they are down to just 3 technical staff (from 5 last week), and two of them are brand new.
