From Solidot.org, Google announced a AdSense referral program. Originally, I was not very interested in the new feathur, because in nearly one year, I haven’t received any check from Google. The click rate on my site is too low. But I think I can just place a button only in this post, and the result maybe is not so important. ^^a
UPDATE: According to this page, there must be only one referral link in a page. So I can’t put the Chinese version button, although the Chinese one is in Simplified Chinese, not Traditional Chinese, which I use.
UPDATE 2: Oh… because there is a existed adsense in my template page, that means I can’t put any new adsense, including this referral link. I can just leave it empty, maybe someday I can find a way to resolve this.
