But there is a certain point t hat if you are hiding...
And you know ICly's you are in a crowded place....
Let's say, the Market Place.
And there is only 2 PC's in it, having a long conversation about toast.
And you type something in and it says,
Someone says, "These two both should be destroyed, for toast is too good for the world. I shall wait until they leave and slay them.."
It seems fair that the market is crowed.
HOWEVER
some ooc common sense should apply to the hider.
Why do you "speak" to yourself?
I realize it's boring watching people talk about toast, but that is the breaks you have to put up with if you want to sneak around and spy on people. They don't have to talk about anything awesome around you by virtue of the fact you are hiding.
Nor do you HAVE to speak to yourself, or do things.
It's probably just me, and before you say, "It's cause you have never hidden after someone."
You are correct.
I have a character who has hide, but rarely uses it.
Because I get better info by talking to people, rather than skulking about after it.

Confusion heard his voice, and wild uproar Stood ruled, stood vast infinitude confined;
Till at his second bidding darkness fled, Light shone, and order from disorder sprung.
--John Milton
