I have to disagree with some of your points. No shade at Orin but WebKitGTK is a volunteer project. Having competition won't push WebKitGTK any faster because I am sure they are going as fast as they can. WebKitGTK already have a good list of features to add because they have other commercial browsers to compare themselves to, it's the speed that they can add them due to resource limitations. BTW, Firefox also runs on Linux. Also, nobody is installing a secondary browser for documentation reading only - what's the point of doing this?
