The value of Wikipedia does divide people, to some extent, but I think most welcome it as "a very good thing", providing easy access to (very largely) reliable material. Maybe you feel you shouldn't rely on it as a single source of authority? In that case, you can always follow the references at the end of the entries.
Speaking of which... I was pleased to see that another Electronics Weekly article is cited as a reference. The latest involves memristor technology (resistors with storage capabilities), and cites our Technology Editor Steve Bush's article "HP nano device implements memristor"
