They actually do respond to requests, complaints that are unique or are addressing a new issue. The fact is that a large % of the requests or compaints are far from new and have been addresses already in the past. Just search these forums and you will see.
Even now they are currently addressing issues of connection problems by changing their service provider from Savvis to AT&T.
There is currently testing being done with the assistance of the community to better improve frame rates.
If your post goes unacknowledged by the staff it was most likely already been addressed before, is being worked on or as HT once said: "been suggested before, sucked then, still does"
(Don't mean for that to be offensive, I just think that response is classic HiTech.
)
