First of all, this outfit is NOT independent - it belongs to Netscape - the fact they carefully conseal.
When I attempted to get our site listed, they messed up and put it in a wrong directory. Emails to editor remained unanswered, so I started looking for clues on how to reach this gestapo-like organization.
At one point, they had a message in my directory stating that they needed an editor. I applied, and was not accepted without any explanations. I have a degree in Computer Science and in the area related to that particular directory... They never specify what their requirements are, never give a reason for denial - what's up with that, and how can they claim their impatiality and independence.
Recently, we wanted to change our main domain, and I contacted the editor asking to update the listing - no response or other reaction whatsoever. At this point, we are forced to have two identical sites which clatters the Web, and technically is not quite ethical - and these people claim to be some kind of Internet Guardian and an ultimate standard of legitimacy.
