I still don't get why wikipedia doesn't do a very simple thing with some of its funds: pay editors full-time. I realise the potential for conflicts of interest, but simply either (i) disburse grants to already prolific editors, to support their efforts, or (ii) pay recognized experts to improve articles which are lacking (e.g. pay historians, philosophers, biologists, etc).
