Free Link Exchange Sites?

i joined smileytraffic, you can check my website in my profile for the link. my blog's unique hits went from less than 10 to 425. the number will be higher if i didn't restrict my counter to unique hits. of course your site's traffic will also depend on how active you are on viewing the sites of the other members. my friend uses easyhits4u.

Http://www.linkreferral.com is the only one I use.
