If you look at Imgur for example you'll see two observations by users: 1) It's amazing and 2) They have server issues. Notice that #2 is incredibly vague and almost hand-waved as a joke. We as developers see the minor flaws but most people just seem to see the good of it.
EDIT: I'm not talking about Imgur. I'm talking about Imgur's posts about Pokemon Go. My bad for the ambiguity.
