Hi!
This is not a technical analysis of this subject; it's just my reaction.
When I think of a directory, I think of a resource with
quality. The website actually points to useful and informative references. On the other hand, I think of a link farm as pointing to a bunch of URLs whose relevance is unclear and questionable.
The
motive behind the directory is to provide a genuinely useful resource for people (and, yes, maybe to make some money

). It seems to me that the motive behind link farms is to simply boost link popularity, traffic and rankings. (Whether it works or not is another question.)
Regards,
Stephen :-)
