I think it has to do with the master account @steem not having enough steem in its wallet to delegate to new users. They dropped the delegation to new users fro 30Sp to 15SP on January 8th.

Thank you very much, that is the first answer I've gotten to a question about steemit in what seems an age.
I checked out your blog, resteems and a follow headed your way.
