Hey you're not alone. If something makes me laugh then it gets a vote too. It is highly subjective. I was just referring to using bots and the issue of plagiarised content. If you don't actually read a post then your not doing any quality assessment.
I agree that these things will eventually get ironed out until they are at least "good enough" if not some other copycat network will come along that does it better and gets it right. (The same way that Facebook took over from Myspace, Bebo, Orkut etc.)
