>In the application it asks for two or three sites.
That is true, it does.
And, if the application is accepted, what are you going to do then? "An editor only HAS to add TWO sites, and I've already found both of them?"
I'll tell you what _I_ did. I said something like, "I've been building a links page on this topic: I've found a couple dozen sites [here are three of them], and I think there are probably another dozen or three out there, still to be found."
See the difference between "do I HAVE to find three whole sites?" and "that was fun. I want to do it again!"
On an entirely unrelated topic, someone once suggested showing by ACTIONS how interested in editing you were. How could you you do that, you suppose?
And one other thing. "You want to help people." That is a worthy goal, and I do not want to denigrate it in any way.
But ... who do you want to help? What do you want to help them do? And how do you want to help them?
Suppose you're interviewing for a job at a bank. "You want to help people." When it turns out that you want to help people who need more money than they have in their accounts, what's going to happen? Or if your soup kitchen job is a way for you to help budding restauranteurs get into business by providing them with free food, what's going to happen?
Again, there's nothing at all wrong with wanting to help poor people or small businesses. The government spends bazillions of dollars on projects alleged (sometimes truly!) to do that, because society accepts those as worthy goals. But that fact isn't going to save YOUR job!
The ODP gives people trusted privileges, for specific purposes. The pay is ... um, below minimum wage. There are a whole population out there (unethical webmasters -- a tiny but VERY vociferous fraction of all webmasters) who are very very intent on having editors serve them and them alone.
Just to give you a measure of how deeply this "me webmaster, you serf" attitude is engrained in some quarters, there's actually a recurring proposal, which is actually popular in some SEO communities, that there "oughta be a law" -- editors shouldn't be ALLOWED to do anything but what SERP perps tell them to do! That rule should be ENFORCED! And if editors don't do what they're told, quickly enough, than ANYONE should be allowed to be an editor. (Anyone, that is, who will do whatever the SERP perp tells them.) For these folk, "suggest a site" is tantamount to "exercise my authority by giving peremptory orders." For them, anything that doesn't force the editor to be responsible to THEM, is called ... all manner of pejorative names.
An editor has to deal, one way or another, with this incessant pressure -- at best self-centered, at worst maliciously vindictive.
How do you deal with it?
There's only one way.
You have to have a clear idea of who the ODP is trying to help, and how it is trying to help them. You have to have a definite mission of your own, which would be helped by an ODP that is more effective at doing what IT does. (Your mission doesn't have to be the same as the ODP's -- for most people it isn't. It just has to be compatible, and you have to be willing to do at the ODP only what will accomplish the ODP mission, and do the rest of the work needed for your own mission elsewhere.)
And you have to have the courage and integrity to deal with as much of the vicious-webmaster pressure as you allow yourself contact with? (THIS can be done by avoiding webmaster contact -- including even suggestions if necessary. Or it can be done by being "as adamant against flint.")
Who do you want to help? And how do you want to help them? And how many webmasters are you willing not to help even when they accuse you of scraping jam from the bleeding lips of the worthy poor?
And then, being so determined, can you stand to work in a community to its standards, or do you need to do your work all by yourself, where you have complete control over all decisions about the mission and the standards?
Ask yourself all this first. And when you're sure of your answer, act on it -- if not on the ODP, then wherever you can. It will soon be very obvious whether you're giving ODP kind of help (or, to be less ODP-centric, whether the ODP contains your kind of help.)
Two final points, that really need to be internalized:
(1) Each of us can do whatever we wish, without the ODP. The ODP is a tool, but it does nothing you couldn't do yourself. (Some things, granted, it does more effectively. But as in many things, "you propose and fate disposes", you act but the effectiveness of your action is determined by other autonomous humans.) Ergo, if you want to do something, you'll do it on whoever's nickel you have.
(2) The ODP can do without any of us. Oh, some of us may help a little or a lot, but ... people who were more productive editors than you or I could ever be, have stopped editing at the ODP ... and it just kept growing. Ergo, the ODP doesn't NEED us.
So then, what's the point? If you want to give THIS kind of help, within THESE limits, ... the ODP will help you be more effective, and vice versa. And if not, there are other places, there are other kinds of help the world needs.
