Yes, we should keep trying new ways to help people. But we cannot assume the solution solves the issue. In fact, we also need to consider new issues that it introduces when the old solution didn't have those issues.
I am not against the change. I am saying introducing changes should always consider the risks and keep the working system to to fall back to. We should always understand the change may not have expected outcome. While staying positive, we should not be blinded to optmism.
And I dislike manufactured statistics. For example, large portion of XP users don't use quick launch bar in comparison to Win98 because users have less interests in it.
