You can also end up with page designers who don't understand a
particular browser's capabilities, and screw up the document served
out to it.  Try movielink.com in Lynx some time:

rosetta-stone-2> telnet www.movielink.com 80
Connected to www.movielink.com.
Escape character is '^]'.
GET / HTTP/1.0
User-Agent: Lynx/2.8

HTTP/1.0 302 Found
Server: Netscape-Commerce/1.12

rosetta-stone-3> telnet web52.movielink.com 80

Server: Apache/1.2.5

Content-Type: text/plain

And it's actually looking *for* the string "Lynx", not just not
finding another string; "Netscape/3.0 (compatible; Lynx 2.8)" will
fail just as egregiously.  Note that the Web server states "200 OK" -
and then doesn't serve anything at all out.

Sorry to ramble on; this is one of the most offensive sites on the
'net, to my mind.
