I signed into wordpress(crossed.wordpress.com) a long time ago, but only a few days ago i injected the script for the g.ads. search box. The theme didn't allow me to insert it .Even I don't think wordpress is on the dark side , I'm almost sure that they don't want adsense users. Or maby I'm a nube. But when I turned to blogspot (joinmynet.blogspot.com) it all ended good, all scripts worked fine. Now another bu, I signed for an advertiser page and the full page addons where divided in puzzels when put on page.
I think you can insert your adsense ads only after 6 months you stick with blogger. but i am not so sure
