There are users who play only for zOMG, this is a fact, not just my personal experience. I buy items to look cool/ridiculous while I'm playing zOMG, especially the ones with "I am" poses. Without zOMG I have no real use for being on Gaia, my home forum is the zOMG forum.
I don't know if you've been to the z! Forum recently, there are plenty of user based events being run, you have to jump ingame and find yourself a crew to have some fun. I have never had any problems finding a random crew, keep in mind you can also start one yourself.
The forums are so ridiculously helpful that every single "how can I unsoulbind my rings" thread gets answered. You get about at least 5 of them a day. I have never asked for help on the forums and not received it.
As for promoting zOMG, that's what we've been doing for the past year. Did that change things? Not at all.
Also by your logic if Gaia is vey profitable, then they should never have to sack staff right? Read the quote I posted in my previous post. It doesn't work that way.
Complaining is a major part of communication, complaining about complaining is just hilarious. The zOMG community needs to let's management know about our feelings, and that's what we are doing, providing valuable site feedback.
