Not another survey...

Here's a challenge for Behind the Spinners... How do you get PR practitioners to fill in an online survey? I am a lead researcher for EuroBlog 2006, a pan-European Survey backed by the European Public Relations Education and Research Association and we are trying to capture a snapshot of what practitioners (sorry, they must be practitioners, not students) think about web logs. It is an adacemic survey that has to be broadly similar across every European country so we can't  incentivise responses (no chance to win a free i-Pod!) but we do need to persuade people to take the trouble to go online and spend about five minutes filling it in. Without giving too much away, the responses from just two countries have dominated the results so far (and no, the UK is not one of them). How do we change this - any ideas gratefully received. And if you have any contacts within the industry, please ask them to spread the word. Thanks, Philip
