Good on most sites, but when you encounter a problem site, there is no way to report it other than the hugely obtuse Reddit.com, where you will find it impossible to either submit a problem or to understand HOW TO SUBMIT A PROBLEM unless you speak 'coder' language.

Utterly useless 'help' section, and the 'instructions' are about as useless. Oh, wait---there are no instructions.

*sigh*
