The times they are a changin'-the Internet and how it affects daily practice in nephrology

The times they are a changin’—this wisdom was galvanized into song lyrics by Bob Dylan in 1963 when computers were still in infancy. It took more than two decades until the humble beginnings of the web in 1989. Since then (and well in accordance with Bob Dylan's lyrics), content and use of the World Wide Web have increased and changed dramatically with now more than 550 billion documents on the web [1]. Not only has the Internet grown—the interactive component and networking have increased as well and the term Web 2.0 has been coined. We have recently reviewed what the Internet has on offer for nephrology [2]. Here, we discuss how these new technologies change and challenge our daily practice.
