Well, the plain underscore in BLA_BLA is indeed wrong but the plain
underscore in the URL *is* correct though escaping it with \ is also
permitted.

Right, you don't need to use \_ in \url{} or \href's 1st argument.
Interestingly, stock `latex-mode' displays the argument of \url{} as
verbatim without subscripting the character after the _. It should do
the same with the first argument of \href.

GNU AUCTeX does the same: _ has only subscript semantics in math mode.
