Making proposals easier to find / organize / work on

I agree. At least Wikipedia don´t need much change, but projects like Wikinews, Wikiversity and Meta do need new ideas. Wikis are very much stable, which is positive but if something went wrong, it is negative. Maybe a short time change in the way a wiki is run, could be a solution. Or we could clone a wiki and change the rules for the new wiki. If the new wiki works better than the old ones, we close the old wiki.
