surfing
     
        ("Internet surfing") Used by analogy to describe the ease with
        which an expert user can use the waves of information flowing
        around the {Internet} to get where he wants.  The term became
        popular in the early 1990s as access to the {Internet} became
        more widespread and tools such as {World-Wide Web} {browser}s
        made its use simpler and more pleasant.
