GT would be great if the posts did not devolve into emotional posts, illogical arguments without data, and ad hominem attacks against posters.
The few times a good discussion happens on GT, there is a selection of posters, and unfortunately they are some of the more active, who drag the thread down with attacks on people or just simply illogical "arguments" that don't add anything significant to the discussion. This is especially true in the political threads.
More and more there are simply threads I don't bother to open because I know where it will end up. I sometimes forget and accidentally open them only to discover that I was right.
It really is too bad, for occasionally there are good threads and people willing to discuss them intellectually. But it seldom lasts.
I wonder how many potential new members are turned off by some of the GT posts?
