Oh, *HELL*NO*!

It's a fucking disaster in "Oh, one notifier was broken, SO LET'S ADD
ANOTHER RANDOM ONE TO FIX THAT".

The definition of insanity is doing the same thing over and over and
thinking you get a different result. Let's not do that kind of idiotic
thing.

Notifiers are evil crap. Let's make *fewer* of them, not add
yet-another-random-notifier-for-some-random-reason.

F*ck me, but how I hate those random notifiers. And I hate people who
add them willy nilly.
