Hi,
They were quite a few expressed thoughts on the 2015 Strategy - Community consultation that raised in a way or another the idea of a "Wikipedia for children". I've made some excerpt of them on the following page : https://meta.wikimedia.org/wiki/Wikikids/Excerpt_from_the_2015_Strategy/Comm...
It actually does exist and are thriving in some languages (especially in Dutch and French, and we actually worked for a while on [[m:Wikikids]]), however they seem to be also some rampant objections. The WMF may not be the most suited organization to host and promote such wikis, is it?
