One of the things that I have picked up from being "on the inside' of the ODp for a few years is the nature of the beast, and why the editors sometimes come across the way they do.
There is a very strong, focused Vision of what the ODP should be. It's is laid out in the the various charters which are public. It's quite restrictive (which I see as a huge plus, because it helps retain the focus), and not very flexible. most editors feel very passionately about this vision, and will defend it, if challenged.
So the issue we have with "suggestions for improvement" is that usually this involves changing the underlying nature of what the ODP
is. This is not something that the people that signed up to the project really want to happen.
If someone believes that this vision of what the ODP is trying to do is flawed, then they are welcome to do it better by starting up another project. If it really
is better, then editors and users will come flocking to it and the ODP will die a natural death as it naturally becomes irrelevant.
The thing is - there have been quite a few who have tried, and, as yet, I don't feel they have succeeded. I feel that this, in and of itself, helps show that, while not perfect, the ODP is the best there is out there right now.
On other forums I have seen ODP editors referred to as "arrogant" - this is often a charge that is levelled at people with vision when they won't bend to the wills of others, and design to the lowest common demoninator. I see it as reaffirming the strength of the vision - keeping the ODP doing what it is intended to do. The fact that this seems to directly clash with webmaster's and SEO's ideas of what the internet should be must not bother us - we are really not there for these people.
All that having been said, there
have been one or two good suggestions made on the forum which have been taken and discussed in the internal editor's fora (which is where most editors stay in touch with what is going on with the ODP - only a few come here). But the majority are just "why won't you change the ODP to make it do what
I want it to. Those, of course, are of limited value, because they clash directly with the vision. if someone wants to be constructive, and really try to "get" what the ODP is about, in order to make some suggestions, then they are more than welcome to, of course (but then I would say that, if they truly understand what the ODP is about, they should become editors
)
