Heej @whiteoutmashups just as a user here who also made a proposal once with another user ;-). Our proposal never made it to the frontpage as well. It started a nice discussion (119 views here in meta) but at that time it was to busy on the frontpage with pinned topics about the testnet that just went live.
The thing is, when your post in “community” is allowed on the frontpage, others should be allowed to post there as well about moderation. Wouldn’t be fair to allow it from you and next week move it to “META” when user B comes up with a proposal. I hope you understand that when you look at it from that perspective.
The thing I would do in your case is just take your idea and drop it @ moderators next to here in META. Just say you want to poll some things, or that you want it pinned on the frontpage. In that case they talk about your idea and maybe allow it for a few days, or maybe not. I truly don’t know the answer. But at least give that route a try if you feel strong about something. You never know what happens ;-).
