I have completely the opposite experience about using Meta.SE. My most upvoted question in the whole network is a MSE question. Half of my top 10 network wide questions are on MSE. Only 1 of my questions is net negative. I don't even have downvoted answershave downvoted answers.
Yet, I can't say the same about meta.AU, and I'm here, participating. That you had a bad experience with a site doesn't mean that a) everybody will b) you will continue having one.
If you think your concern is of the entire network, or that impact the whole networkimpact the whole network, afraid not, any meta will do.
