I've seen a lot of blog posts today about how English Wikipedia is preparing to get the FlaggedRevs extension installed. I think that's a good idea, English Wikipedia is a project that could really use it to great effect to improve it's reliability and decrease it's spam volume.
At English Wikibooks we've had that tool for a while now, and some of us are starting to question whether it's suiting our needs appropriatey. There have been plenty of complaints about our autopromotion requirements for +Editor (I can't even tell you what the current requirements are, since they are so complex). I've advocated drastic reduction of the requirements (after 10 edits or so), although some people have said that we should just tack +Editor on at the same time members get autoconfirmed, which is a simple 4 day timer. I like that idea too, although I'm not sure it is going to perform the promotion quickly enough.
We've also been worrying that we don't quite have a large enough community to support this tool anyway. The list of pages that have been reviewed is certainly growing, but it's woefully small compared to the total number of pages we have at Wikibooks. We just aren't reviewing pages quickly enough, and I'm not even sure that we're reviewing pages as fast as we are creating them. Of course, if we have more +Editors who are automatically sighting pages with every edit, that number will increase pretty dramatically.
Also, as if we need more factors to worry about, we need to think about whether or not our current grading metrics are sufficient. We have three metrics now: Composition, Accuracy, and Coverage. These are nice, but they don't necessarily cover all the things that we might want to look at. Also, I find there are lots of areas of overlap: Accuracy tends to go up as we get more coverage, and the quality of writing goes up with volume too. Being more accurate also requires more precise and higher-quality writing. In short, it's rare to get a bad grade on one if you've gotten good grades on the other two.
We have questions to ask, and questions to answer. Plenty of things will definitely change, and maybe we as a community might decide to uninstall the extension entirely. We'll see how things play out.
