I'm wondering whether we're all confusing "standard-bearer", the person who
carries the standard, "a flag; colors; a banner; especially, a national or
other ensign", with "person who creates standards".
If the meaning is taken to be the person who acted as flag bearer, or, in
90's media-speak, a spokesperson or talking head, then the choice of
Andreessen makes sense, since he was very much the Web poster-boy in the
early years of Netscape.
