You should write with more appropriate English. Your current one is bad-written--English, so it's hard to understand what you wanted to imply. Furthermore, I don't think that you should create such a topic (of I do understand what you wrote).
Oh, get off your high horse. The OPs English is considerably better than yours. My guess is that they are a native English speaker although using an informal writing style with not much punctuation.
As for the actual proposal: meh. I think merit primarily pertains to individual posts. A thread might have a couple of meritable posts near the beginning but nevertheless degenerate into a spamfest.
