	Although I know very little about gopher (except how to use it),
I believe that Mosaic/lynx has essentially made gopher obsolete.  While
gopher was useful in its time, Mosaic/lynx allows one to do so much more,
so much more easily, and with so much more flexibility, that time
spent on earlier protocols is essentially wasted now.

	From the Mosaic point of view, you would put the biological
program inside of mosaic, rather than vice-versa.  This is what the
NCBI has done with their wonderful Mosaic entrez and GDB has done with
there new mosiac GDB brower.  Because Mosaic offers the capability of
running over the internet or running off of a file, (as on a CD-ROM),
Mosaic provides a platform independent front end for other programs.

	I don't see the difference between lynx and gopher for dialup
lines.  With 14.4K modems running less than $150, there aren't many
slow telephone lines anymore.

	If you have more than a screen of contents, you want to be
searching for the topic, not paging (that "table" of all the gopher
servers in North America is one of the most unpleasant things about
gopher).

	It is, of course, trivial to provide the file-cabinet view
with hypertext.  For the kinds of things that I want from a database,
hypertext is far more useful.  In particular, GDB's methods for
searching the genome database, showing a record, and then providing
hypertext links to all of the fields in the record, is far easier to
use than any non-hypertext presentation I can imagine.  It is
certainly much nicer than the older direct viewers for the database.

RE: David Steffen's comments -

	Mac Mosaic is by far the more robust of the DOS/MAC Mosaic
implementations.  It is the Window's Mosaic that is bug-ridden and
difficult to use (partly because of the problems with Windows
networking).
