UPDATE 3
After all this I have been banned from asking questions, presumably due to the down marks I received from this question and https://meta.stackexchange.com/questions/100529/help-us-clean-up-the-android-tag/118975#118975 where the OP requested ideas to improve the android tag. You can't help but admire the irony.
ORIGINAL
My problem is:
In an attempt to squeeze meta into the standard QA model of stackexchange I believe a site has been created which slows down evolution.
Meta seems to be made of of established users and established users are more likely to be those resistant to change to a system which got them their status in the first place, new users with fresh ideas (I am not talking about myself as I haven't had any yet) take a greater hit from this down voting system as they have less rep to lose.
Any radical or unconventional suggestions are much more likely to get down voted and so there is a disincentive to make these suggestions. Some might say that the formula of the site works and I certainly agree with that to an extent but you only have to trawl the android and facebook tags to see there are serious problems which need fixing and as these are two of the newest technologies and as more hobbyist will come on board Stack Overflow it is only set to get worse.
This voting model wasn't set up for discussion and this is a symptom of trying to make something work that wasn't intended to work like that in the first place.
Should the voting system for meta be changed?
UPDATE 1
In response to Robert Harvey's point I would point people towards the monkeys in the cage. Although I agree with some of his points I also think this is the philosophy which for fills my original point about resistance to change.
Pekka's Points about Meta votes not being valued moots my point but leads to the obvious question: why do they exist and why isn't this point better documented.
On a side note I hear a lot of people saying
It's not a big problem so why worry
But problems such as duplication, noise, unanswered questions, poor question quality will most likely not be solved by a silver bullet but most likely a series of small changes which steers stack exchange away from these problems so I am not sure these answers hold water.
UPDATE 2
As commented the down voted answer which triggered this thought in my head was in response to a question requesting suggestions, to lose the very little rep I had at the time having been prompted to provide suggestions just seemed perverse. I have since discovered that both voting and discussion in general has little or no value in meta and so that has cleared that up.
