Ok, first of all, we need a definition of spirit here and not view it as an abstract thing. "excellent disposition or attitude in terms of vigor, courage, firmness of intent, etc.; mettle"
One of the major things you forget about our server is that on average we have around a 40-60 peak and PO has a constant 900+ peak. There are a lot of things that you can and can't compare between the two. Does PO have more spirit? yes... I bet in total they would because they have so many people. What we have is more special. Our users individually however definitely care much more about the community here than almost any other server. This explains a lot of them defending this place so greatly.
We are a much more spirited community than we are battlers and it shows pretty well.
As far as tournaments go... we actually have a pretty good variety of tiers, at least no worse than any other server. What you need to remember is that most people play OU and with our tiers, it is the most inviting. ALL servers have a much greater amount of OU tournaments when compared to other tiers for this reason. When people ask for other tiers, it is granted very quickly. Can this be varied more? of course but there is no way that other servers (at least others I have been to) vary it any more than we do.
Also, I definitely agree with what zen said about the small decrease in gg's after tournies. It is much better for us to address the ones yelling at our tiers so that they can better themselves than to congratulate the ones who should already be feeling good imho.
As far as the business with kiozo went, I am sorry but you definitely blew it out of proportion and are taking the wrong response to it. As far as the metagame goes, moody is definitely one of those things that frustrate users and hence it being banned elsewhere and discussed about being banned here. It is very looked down upon by a lot of battlers. This is not to say that it isn't viable but it certainly isn't something that a lot of people would taught. Kiozo did say the wrong thing as you were right about moody being allowed according to your story, but it also seemed as though you escalated it. You seemed to push the tiers in his face instead of calmly saying your point. Other people jumped to his aide because of this common mentality NOT because he was a mod.
Finally, standing up to a mod is something that you should very rarely feel proud about, no matter how justified as it suggests the need for something much darker.
EDIT: sorry, didn't mean that mods/auth shouldn't be challenged as they should when they are out of line, just that it probably isn't something to be happy about imho... sorry
