Ok. I can go further... (to be taken in a nice way) Yes, there are a lot of discuss for sale but not many have sold for the price they are asking from what I can tell. (looking at sedo, namebio, etc).
Furthermore depending on what niche you are looking to target discuss gas may not be the best keywords / domain name that you could find for the price. That is just for purely the domain name and the reg fee comment. At first I too thought it was a great name but after researching the alternative names and what others are selling for my feelings changed.
Now I think if you could throw a forum on there or develop it I think it could be a winner.
Hope this helps. Keep trying. I do...
