Refer a friend to .Mac, collect $15

Apple just launched a new .Mac affiliate program
that pays users $15 per subscription they generate via referral. Commissions are generated by including special URLs on your blog or web site. As with the affiliate programs at the Apple Store and the iTMS, marketing for the referral program is being handled by LinkShare.

I don't personally use .Mac; do any .Mac users want to weigh in on their experience with the service? Also, I would love to hear reports from folks using any of these affiliate programs; is there money to be made for the average blogger or site owner?
