evidence for the proposed measure of community strength?
Wow - that's a pretty strict definition of active... it's about 300% more strict than we're using anywhere else on this wiki (5 edits per month).
Do you believe the trend would be any different at a different activity threshold? If so, why?
I have to say, I've never been so keen on 5 edits per month being the definition of active. That's incredibly few edits. I know it's always really hard to draw lines and any number one comes up with is going to be arbitrary. But five edits is just a little over one a week. And, really, how much can be achieved making one edit a week? Five edits would barely constitute one sweep of a day's changes on a watchlist of a thousand articles.
Obviously ONE edit could be the drafting of an entire new article or an entire draft policy that becomes a tremendous boon to the project, but I suspect people that do that kind of thing are also people who make a large number of edits.
All that said, I don't propose we change it now!
There is some evidence that using the 5 edits per month will show less attrition, based on other attrition statistics.
I am not really interested in playing numbers games... what I *am* interested in is making sure that whatever numbers we use are real; using comparisons of different measures without consistently using the same comparison is questionable from a metrics point of view....
