Well, we have a longer description on our site about what we are about, but here's the short version.
1. We don't censor stuff unless we legally have to. By the same token, you can trope and discuss hentai games and other adult works so long as you don't do so while typing with one hand. Just stick to the facts and keep what gets you off to yourself and we have no problems with that material being discussed and pages made for it.
2. Admins are not gods, the rules apply to us too. In fact, I myself personally have stepped down over incidents where I was in contravention of the rules, even did so willingly to set an example, and would happily do so again. We also are not above getting called out for screwing up, so long as you do so in a civil manner and bring up legitimate grievances concerning technical issues or bad admin decisions. Dissent is not treason as far as we are concerned.
3. We have a forum, but it's strictly limited to on-site related matters only. We decided the unfettered forum TV Tropes had caused a lot of the problems we wanted to avoid, like nasty fights over politics, creepy sex based RPs, and non site material can easily be discussed in other fora anyway.
4. We are transparent about enforcing the rules. None of that "closed doors decisions" crap unless it involves private information or legal matters that require discretion.
5. We go out of our way to be hands off on rule enforcement and being nice to newbies, as all of us despised what we saw as ironfisted BS on TV Tropes we wanted to get away from.
6. Finally, we are an alternative to TV Tropes, but we have no objection to people posting on both sites (though you have to be mindful of certain copyright rules when doing so), and we keep in touch with TV Tropes, as neither of us wishes to cause the other site undue trouble and have and will cooperate to deal with vandals and troublemakers that have plagued us both.
