How about some performance hacks for HTML+
One might be: <A HREF="..." FREQ=44>
Where FREQ is the probability that a user will select the link.
Of course, the browser would be free to throw in factors like the
user saw that yesterday, he might not want to read it again today.
This would allow browsers to fetch information in the background whil
the user is reading.
The FREQ data could be static (computed by the author) or it could
be added on the fly by the omniscient server :-)
