Maybe someone else is interested in my "personal wiki" I implemented
on top of org-mode.

It basically adds three things to plain org-mode
* Narrowing
  Makes only current section[*] visible and thus avoids any distraction
  by unrelated things.
* Automatic links of all text matching a section name.
  Much like org-wikinodes, but without camel case.
* Navigation history
  When visiting different sections in the same file history is
  recorded allowing navigation "back" to previous section.

Find the el file attached, and also an example file.

What do you think?

[*] A section is the contents of a first level heading.
