So here's the opposite to the "Pet Hates" series - ideas that I see in use and think are neat.
Glooo.co.uk would be happy if you filled their contact form (assuming you want to contact them about something sensible, I suppose). But people don't like filling out contact forms. So Glooo head their form with a big bold statement "Less than 2% of visitors will fill in the form below". We all would like to be in the top 2% (ideally in the Wall Street sense, perhaps, but you've got to start somewhere....). My guess is that it works, and in any case it is amusing...
