	Unlike some of the stuff recently discussed about having a summary, the
Alt tag is already available to the visual user. It may be more logical if
Alt didn't display, but instead Title or Caption did ... but since Alt
displays, visual users use it ... If Alt continues to be all that displays,
it's function is likely to change as the web develops.

Like the Alt tag, Summary is likely to prove very popular as the web
develops, not just for the slow folks it starts out to suit, but also the
speed demons and site surfers, who like to lite and go....
