1) Having a large staff is the opposite of radical change. 2) As a former WMF staffer - let me tell you they are well aware of the issues mentioned by Halfaker. They've been commissioning and releasing studies like this since 2009. They all had the same conclusion, that 2007 was the point where the community shifted, from collaboration to make cool stuff, to defense against vandalism. It's not clear what the WMF can do to change this, without engaging in a "takeover" of the community or completely changing the model of how the wiki works. The former would alienate everybody, even the editors who want change. The latter is technically infeasible; even if they wrote new tools from scratch, Wikipedia interacts with everyone else's tools and plugins. Even if you change the id of a div you'll probably have a thousand people screaming at you the next day. The WMF can propose that people be nicer, or write tools that are more welcoming to new users, but all that means is that you get to have your edit rejected with a prettier icon. The main problem is in the edit cycle itself, not the tool that's used. Many editors think that Wikipedia is basically done, and repelling new users is actually a good thing. They aren't bad people -- they just think that encyclopedia quality is far more important than growing the community. So when they see something that seems wrong to them, they revert. Reversion, for Wikipedians, is really how they open the discussion. You're expected to keep going if you think your edit is good. But because we have a linear edit history, with only one live copy of the article, it feels like a slap in the face to the new user. Things that would pass muster for weeks or months, in the past, are reverted instantly. Often times the criticisms of the new edit are justified, but the standards are ludicrously high now. You'd better be ready to cite everything rigorously and be familiar with a zillion policies. Not all of them are like this, but enough to make a gauntlet for new users. And those new users just go somewhere else.
