[wiki-research] Link density in wikis

[Filippo A. Salustri]

A word of advice:

Make sure you're running TWiki on a pretty powerful server.  I like 
TWiki alot and have played with the directed graph plugins.  I found my 
computer would literally run out of memory trying to process a 
moderately-sized collection.  This is the *only* task that can max out 
my computer.

Cheers.
