Personally, I just quit editing after 15 years (12 as an administrator) in protest at the deletion of good encyclopedic content. Frankly, I can see clearly why new editors don't want to become involved in Wikipedia - the community these days is positively toxic. I think, subconsciously, I was rather hoping someone would fix the problem and invite me back, but not only has the problem not been fixed but nobody seem to give a damn. There was a time when I even attended Wikimedia physical meetings with governments and academics and so forth. Well... no more: so long, and thanks for all the free edits.

My solution? Remove all the bullshit policies, reduce things back to a core of spirit-of-the-word driven basics, and then have a random selection of a panel of community judges (extra/uninvolved eyeballs) for anything at all that people want to dispute. This would do far better than the mob rule of yore, while lowering cognitive overhead and friction for new editors.
