I think the orher reason is: Its not important to get publishers only they also need advertisers otherwise all publishers will get PSA's and they will leave.
Yahoo Knows everyone is going to try them which means almost billions of pages showing ads....are their so many ad ready to be shown.
So I think it will grow slowly but I am sure they will take more pubs very soon.
