the 10 posts isnt because they need the 10 posts. But because they want to ensure that the beta testers are involved, and make sure the people that test their game actually care. - If you see the 10 posts as "just something that needs to be done fast as possible" then you are missing the point. Forget about the number "10", and just be part of the community - That is what the devs are asking of you. - if you dont want to, then esentially you arent what they are looking for.
I see it like this: If you have a kid, that needs to be tested for something - you really want to be sure that the doctor testing your kid actually wants to, cares, and know what he is doing ;)
