For threads that are for main features of the site, the first post has a minimum word # requirement.
So for example, the first comment for a new ZP episode must be at least 100 words long. Then the second, third and fourth must be 75 words long. Then the fourth through tenth must be at least 50.
That way, the first posters HAVE to come up with something useful and meaningful to say. Until someone whips up a good post, nobody gets to talk.
Perceived problem #1: "That would be awkward and unfair; bringing the community to a sluggish halt just to get the first few posts off the ground."
But with this concept in action, I promise you, people will be scrambling to be the first ones to post. It will give one all the same great excitement and honor of being first, multiplied SEVERAL times over, because of how hard the title would be to achieve. The first ten posts will get made in no time at all.
Perceived problem #2: "But... wouldn't most people just spam 100 words into their post, just like how they spam a very short, quick post now?"
I can't say why exactly, but I just know that that wouldn't happen. I guarantee you. Not nearly as often, anyway. I dunno, I just have a feel for these things. A potential spammer would be extremely hesitant to manufacture a 100-word post with completely random brainfarts that make no sense; it's a very obvious, embarrassing crime. The fact that "First!" or "Haha nice vid!" or "Yay a new Movie Bob!" is done so frequently is because it is a short, quick act of vandalism that the poster can justify to them self very easily. A 100-word spam fest, they can not.
Now 90% of them WILL just sit down for a minute, think super hard and force themselves to come up with something to say that will just barely get by the mods. So sure, it won't be natural. They would force the ideas to come to them within a very small time constraint. But you know who else forces their ideas to come to them within a very small time constraint? Trey Parker and Matt Stone.
Edit:
It seems whenever I have a totally sweet idea and tell the Escapist about it, it gets shot down by everybody because none of them can take the greatness. And then I have to spend HOURS responding to every little nitpick and variable; most of the time it's just the same three arguments being made over and over again in slightly different words. So, just a little advice, if you come up with something to discredit this awesome idea with, first read through this thread. If you see somebody else already made pretty much the same point as you did, just quote or snip-quote their comment and say "I second that." It'll save me a lot of time.
