Fine, you kids are entitled to your misguided opinions with little or no actual experience with trying to operate/run one a site such as this.
But, surely as 'kids' as you would so condescendingly put it, we would know what people our age would prefer.
It's much easier to communicate someone via live chat, rather than comments or forums.
And what, perchance, makes you believe they are so much larger than us?
Well, seeing as we don't know how much people play here daily, since we have no reference, but:

I would be surprised if we even had half of that much users on now, at this point in time.
And it is clearly just the chat which makes it 'way larger' than AG
Their OT, while much more spammier than our Tavern, is much, much more active.
So that statement would be false.
You could have a billion people here and only have 10 or so active
With every extra person playing, it increases the ratio and possibility of activity.
I hate huge chatrooms. They're always the noobs that'll hop in and ruin everything.
'Mute.'
Here you have time to formulate your opinions and you can try to sound smart, as opposed to a chatroom where you have to spit out replies faster than you could possibly imagine.
Then that isn't really you as a person, at least in a chatroom, you get to know the real person, if I was to think out my post for more than a minute, rather than just smash it out typing, I would look over my posts and say to myself:
"What a tool."
