Oh who made you the judge? I think he has added more to these discussions than you have? And why wouldn't he have some bias towards an item he created and is invested in? Or do you want nothing that puts up a defense for "their" side.
Bah, I'm probably preaching to a choir here....
I'm not acting as a judge on anything, I'm just giving my own personal advice based on what I'm seeing in the situation.
Here's the fact of the matter - his angle on Sony's hardware and engineering is no more informed than anyone else's here, aside from maybe some of the Sony insiders. Therefore,
he adds nothing of additional value to these discussions compared to any typical console warrior. Add to that his status as an MS representative on these forums, and it becomes easy to paint him as obviously marketing his product on misinformation and trying to twist the truth - regardless of whether
you personally think that, he's opening himself up to be criticized by others for that very reason. It poisons his image, and that of MS reps in general, and that's not something he needs to do to himself at this point.
That's why I've said numerous times in the past - MS can use their presence here to open a direct line of communication between fans and the Gaf audience to someone directly related to MS. That's actually very powerful, and can be very convenient for both sides. Something like a few weeks ago, where we were able to get direct clarification on the Kinect functionality issues in some of the launch countries, that's
exactly the kind of cool thing that we get out of this (even if I'm disappointed that there's still no "official chart" to come, but I remain at least hopeful that it's somewhere in the works...) and seeing more of that would do well to build back up some good will toward MS. However, that's not going to happen when it's very easy to point to some of his posts and just say "he's pushing his agenda on the forums."
So that's why I say, he (and Nelson, and any other reps - MS or otherwise) should stay in the sidelines in these debates. If they want to correct outright lies, fine, but trying to add their own piece to these discussions in particular frankly does them no good.
