The problem
with having it in the root
directory is that the url for the file "index.php" is the same as the
url for the article "index.php", which makes everything rather
complicated.
I don't understand that logic. Whether I put everything in a
subdirectory or not, all the wiki installation is in the same folder,
hence the url for the file index.php will be the same url for the
article's index.php. Whether it lives in /wiki, /w, /bozo or /root,
it'll all be the same issue, won't it?
Null article path is evil (i.e. risky/dangerous); it causes confusion
between wiki pages and server files/folders.
For example, try accessing the robots.txt or favicon.ico (for the
uninitiated, those are two rather crucial files that should be present
and accessible on any Web server):
http://docs.jquery.com/robots.txt
http://docs.jquery.com/favicon.ico
That will lead you to the respective wiki page, instead of to the file
you actually needed.
I guess there are a number of other issues with this as well, but I'd
have to ask Brion for details.
