User Experience Community
An improved User Experience is in many cases the driver behind SAP NetWeaver Gateway projects. SAP launched some time ago a special community arround this topic. You can find it here: http://experience.sap.com.
In this community there is more information about SAP's User Experience Strategy, SAP Fiori, Responsive Web Design and many other interesting topics, more from a user experience point of view and not too much from a technical point of view.
I also just posted a blog about SAP NetWeaver Gateway in the User Experience Community: https://experience.sap.com/post/show/131.
