That would be definitely good. I have got a similar idea several months ago, more comprehensive I remember, but unfortunately I can’t remember it clearly now.[1]
Considering the target of the wiki, I think both normal users and advanced users can be covered, given enough resources: just put information of different levels in different pages, with a link in the basic level article to the more advanced one, or just put them in the same page under different sections.
As to the structure of the wiki, I think the one of ArchWiki and Gentoo Wiki is fairly good. Softwares have their own pages, and general topics like blocking ads have information about different suitable softwares and other aspects in other pages, etc.
