Chapter 2 procures the basic principles for Web-based information and expe- rience exchange. To this end, Sect. 2.1 outlines the most important Internet services. Trends in the Internet, known by the name Web 2.0, are displayed in Sect. 2.2; in addition to that, a classification of social software is given. In Sect. 2.3, a list of criteria for municipality Web sites allows to make an estimate of the content. A gross architecture for more ample eGovernment portals is pre- sented in Sect. 2.4. The guidelines for barrier-free Web access were created by the W3C and constitute the basis for all public Web sites (Sect. 2.5), with the goal that people with mental or physical handicaps can profit from Web-based information and services as well.
