Earlier quoted context omitted.
I like RESTful APIs too, but it's silly to imply that anything else is wrong
I'm not sure the implication was necessarily that it was wrong, the poster (no pun intended) could have meant that it could simply have been better to use GET.
That's right: I wasn't implying it's wrong to use POST, merely that GET is clearer, since using it would make it more obvious that the query isn't changing the state of the server.
