Options create anxiety. When people are trying something new its extra-important to remember this, because theres already a built-in level of anxiety when trying something new.
This is particularly applicable to the KDE project, which struggles with featuritis and interface clutter. New users are already in generally unfamiliar territory with KDE — throwing a zillion toolbar buttons and menu options in their faces doesn’t help alleviate the discomfort created by unfamiliarity.
For the record, I use KDE frequently, but that doesn’t mean I think it has a great out-of-the-box user experience.
