Yes, many user don't know how to "do" content negotiation. However, 
servers do content negotiation, even if the users don't know. A very 
large proportion of user-agents lists at least some media types in the 
accept header and puts at least one language in the accept-language 
header. So what is the "default"? The variant that you get if no accept- 
  or cookie headers were sent? This is _not_ what most users will get.
