The old affiliate script was at:

http://l-stat.livejournal.com/js/pagestats/DR*.js I personally noticed sometime very recently when I started to have trouble clicking on links and having them work, since I haven't "opted out" at this time and because as a NoScript user, I have LiveJournal Javascript whitelisted, but not outboundlink.me. I think what happens because of this is that the script hangs looking for the response from outboundlink.me, which never comes because NoScript won't allow it.
I imagine the next logical step for LiveJournal and Driving Revenue would be to make a subdomain, such as outboundlinks.livejournal.com, to use to point to Driving Revenue's service, instead of using an external domain like outboundlink.me.
