This year started well... I have one mid 2x,xxx end user sale in escrow right now, and a couple of other promising negotiations going. Last year I hardly sold anything, but I don't really try selling anything... I just sit on the domains, and wait for buyers to contact me. (Usually via whois info, or via contact forms at the domains themselves.)
Only 1 in 50 or so are end users, most are obvious domainers, and when I get a $100 offer for something like an LLL.com I don't even bother. (Especially when I get similar offers on several premium domains, who all just happens to be perfect for the guys "high school project" or something similar, then I'm about to puke.)
But if the initial message is intelligent, seemingly from a reasonable person, I negotiate.
Before doing so, I try to dig up as much as possible on who I might be negotiating with... Not always easy, but usually it's possible to find out at least something.
