I'm currently in the process of inventorying and tagging beginner material
It looks it is somewhat outdated. One of the thing I noticed is that the
knowledge progression of some contents is disconnected or unwisely
connected to the others.
To improve that at some point, I plan to build a tree of knowledge for web
technologies. Before moving forward, I wish to know if some of you know if
there is already such a tree of knowledge somewhere ? I don't really like
to reinvent the wheel :P
