I also find navigating by heading to be efficient -- in fact, if the
first heading begins the main content of the page, I find it to be the
quickest way of getting there with JAWS (Just one press of the H key).
I seem to get better results with the skip-navigation huristic of JAWS
by doubling the default setting from 25 to 50 characters.  This still
often does not work, however, so I appreciate a skip-navigation or
jump-to-main-content link when heading structure is lacking.  

An advantage of the JAWS "quick navigation keys" like H for the next
heading or N for the next non-linked text is that they can be pressed
during the initial continuous read of the page, and the reading will
then continue after the navigation.  This is most efficient, as it
eliminates the need for separate keystrokes to navigate and then read in
context in order to know whether the skip-mavigation attempt worked.

Regards,
Jamal

I seldom use skipnav links anymore.  With Window-Eyes and IE6, I try to
go 
to the first heading or to the first block which has two or more lines
of 
two or more characters, then look around with the MSAA cursor.  The
default 
for this "next text" command in Window-Eyes is 1 or more lines of 1 or
more 
characters, but I found this to often pick up the text between nav
links, 
so I changed it.  I think the default for JAWS is 1 or more lines of 25
or 
30 characters, which is probably not a bad heuristic either.  It would
be 
really useful if more sites would using headings in a semantically 
meaningful way, but I'm preaching to the choir by saying it here.

I use Lynx to get a good text rendering of some kinds of web pages, but
for 
table browsing and interpretation, the IE/screen reader solutions work 
much, much better.
