I haven't noticed that much 360 hate/potshots, but then again I rarely go to the X Box forum and don't go to many 360-centric threads in the Gaming forum. Where I do see a lot of bashing is in the comments posted beneath the weekly chartz. It seems the PS3 gets a beating quite a bit there. I also notice quite a few childish comments about the Wii in the comments section(as well as some 360 ones). I don't often say much about any of it, as I feel their childish comments discredit the posters enough, and it the mods responsibility, not mine.
Since this is going on in the 360 forums and you're a mod, take care of it. You don't need to explain yourself for taking actions against people who bring the forums down. If people aren't adding to the discussion and only complaining about how they wish it was happening for the Wii or PS3, tell them to cut it out. If they keep on, ban them. They may not be flaming, but they are dragging down a thread by adding absolutely nothing, only whining.
If this kind of crap is eliminated the forums will be better for it, but I also will expect the same kind of moderation in the Nintendo forum. There are a few users who don't usually flame, but like to come in and make irrelevant, off-handed, snide, passive-agressive remarks quite a bit. I don't say anything about them because...
There seems to be a bit of X Box/Sony coddling going on here. I realize the forums should be unbiased, hell the whole world should be, but it seems in an effort to appease some disgruntled X Box/Sony fans, some things have happened that I don't agree with. I won't go into details, because maybe some feel it's a necessary evil for this to happen. I can understand that logic, even though I disagree with it. This site needs to grow, it should grow, and deserves to grow to the point that it can be a self-sustaining and profitable effort.
Maybe being a Nintendo fan has just hardened me to the mockery from the peanut gallery. Perhaps that's the real reason I let it slide off my back. Being a Nintendo fan I've become used to ignorant mockery and biased forums, so I tend to ignore it more than complain.
Overall I think things here run pretty smoothly. This is my forum of choice, my home. I would rather see some more aggressive moderating, but I realize that is something you have to be careful with; modding people for derailing or attempting to derail threads without flaming could easily turn into a "thought police" sort of situation with some folks. It's a sticky situation, but on the whole I think almost everyone here does a great job. Just remember, no forum will suffer if idiots are banned. :)
