saw something that said 'please upgrade', with a quick painless link to do so, would upgrade.
What about folks who peruse the web for their job and don't have the rights/permission to install new software? I'm not infatuated with Lynx, but why not support it if you can still offer all the eyecandy you want at the same time?
personally, i would much rather use javascript to do these things, instead of, say, Flash, or Shockwave.
I would much rather use CSS for as much as can be done with it, and Flash for what cannot.
But hey, maybe thats just me, maybe everyone else loves programming GUIs in flash?
I write GUIs in GtkPerl and sites in XHTML/CSS.
