The bigger the forum, the more action and the more lime light. It's natural. If Microsoft and/or Apple was a 3 man operation, we wouldn't hear a thing about them.
The Z is part of Gigathreads which is pretty big so it is well know in the forum industry. One of things that comes along with being big and growing is 'talk' and talk will have both praise and trash. The more that's going on, the more talk there will be.
Personally, I kinda like being part of the one that's talked about the most.
