 Introduction
 ============
 
-In several hypertext systems today, following a link means a disruptive change
-in the user's workflow, replacing the current context with an
-entirely different one.
-The reason for this is that most systems still use the paradigm 
-(developed in 70s at Xerox PARC [XXXref]) of
-overlapping, rectangular, *independent* viewports to paper-like documents ---
-A link operation can only create a new window or switch the contents of an
-existing window.
+In several hypertext systems today, following a link means a *disruptive* 
change
+in the user's workflow, replacing the current context (e.g., Web page) with an
+entirely different one. A focus+context view [XXX] of bidirectional links
+can provide a *gradual* change by showing fragments of link targets
+before a link is followed, and fragments of link sources after
+the link has been followed (if links are bidirectional).

+This is diffucult to realize in the dominant graphical user interface paradigm
+(developed in the 70s at Xerox PARC [XXX ref]) in which *pages*
+are shown in overlapping, rectangular, unconnected viewports (windows).
+In this paradigm, following a link can only create a new window
+or replace the contents of the current window.

 Alternatives, such as replacing part of text (XXX antont's reference),
 are not very popular nor intuitive... [XXXref]
