Good morning, blindnoob, good question.
I, and probably a lot of other editors, originally joined the ODP for just that purpose, to get our own sites listed, and there's nothing wrong with that, as long as you stay totally impartial and treat your own site the same way that any other site is treated.
In my case, once I became an editor and saw what it was really all about, my goals changed and I wanted to be a part of such a great community of people and what they were trying to do.
Even though I had the right to list my own personal site in the category I had permission to edit in, I didn't. In order to show complete impartiality to my own personal site, I asked a meta editor to review my site suggestion in my place, and she was happy to do so. Meta editor mapfan, I believe.
What I did wasn't neccessary or required, but that's how strongly I feel about impariality and fairness in our editing responsibilities.
If my site had belonged in a category that I didn't edit in myself, I would not have requested a review for it, it would have been treated just as any other site suggestion is treated, and it would have waited right along with all the other site suggestions in that category.
