Nice idea, but there's a bit of a fatal flaw with the poll.
For people like me, and I understand there's a few of us around, it's impossible to answer without lying.
I don't like crossovers and rarely read them even if I like both series involved (eg Doctor Who and L&C). But I can't respond to the poll unless I tick at least one option in the list of crossovers that I would read.
You need a 'don't like crossovers' ticky box
