How does this indicate that they can't be watching the suggestions on GTPlanet? Just because it isn't executed doesn't mean they can't be watching it.
Apparently some of you think watching and executing is the same thing, let alone expecting PD to somehow execute every single suggestion like it's a simple thing. Even if they're not "listening," that doesn't mean any less that they're not "watching." Eventually, the final decisions are all held at PD offices. Not every suggestion is going to turn out to everybody's liking.
Besides, it's common practice for developers to look at people's feedback and suggestion. It would be more baffling imo, if they don't. The question should be, "Why wouldn't they look at one of the biggest and well known GT website?"
