Seems like bad use of time.
Also, making harsh statements and then back down when someone calls you out on it is not really what I consider nice either.
But this is Phoronix, and we are speaking about GNOME so who cares about manners or facts, right?
I have noticed that a lot of Linux users seem to like to whine about new stuff.As you probably noticed, there's much more criticism after gnome shell appeared.
I have seen it with NetworkManager and with PulseAudio, and a bunch of other stuff. So you might see why I don't think "there are a lot of criticism after project X appeared" is a good measure of whether project X is actually going to be succesful.
