Your third paragraph had some good points, but I still voted no. I think the rules are well enough accessible and explained that they shouldn't be a problem to follow, regardless of posting frequency. It's their house we're pooping in, after all, so they have the right to tell us not to do it in the sink.
The only rule here that bothers me at all is the low content rule. Sometimes, a couple of words is all you need to make your point, but you'll get nailed if you keep it low. The favor seems to be for the literal amount of words and not for the amount of content within the words.
I think it discourages concision - which in and of itself isn't a bad thing; I understand that concision can discourage discussion as well, and discussion is the main priority of these forums... but I'm a fan of brevity. I'm also a fan of succinctness, and wit. Brevity is the soul of wit, or one could say that they are synonymous, meaning that they mean the same thing, or are close enough to be liberally used interchangeably. These forums sometimes like those qualities, because an idea that could be perfectly communicated with a word or two, must be unrolled and dissected into at least a sentence to meet the mod's standards. This causes further problems, because sometimes when you unroll a couple of meaning-packed words into a sentence, it loses much of the impact and some of the meaning, and you have to keep writing sentences to fabricate context that would have been pre-established in the tone of your original comment idea, but was destroyed when the tone got changed with the comment's structure. Before you know it, you have a paragraph. This massive, long, unending string of sentences that doesn't come close to having the impact, meaning, wit, conciseness, succinctness, brevity, punch, pizzaz, provocativeness, depth, electric boogaloo, bite, panache, coolness, clarity, terseness, or sweaty rightiousness of your original idea. For instance, everything I've just said could have been said in one word. Can you guess what it is?
