One thing I ought to say, and haven't: While I disagree that a multiple choice Perl quiz to ascertain whether someone has ascended to or past the level of beginner is a "good idea", I commend you on the notion of blogging about Perl.

People of all ability levels who enjoy programming with Perl ought to be shouting that from the rooftops. Once you iron out the kinks, you may want to participate in the Perl Ironman Blog list.
