Like to see some true 'nail-biting' advertising.
Simple, powerful, no tricks and no special effects.
This one ad put Union Carbide on the map.
Watch the Birdie!

Pay it forward...

Here's a great example of a brand complementing or thanking its followers.
In this case the brand is Australian Singer songwriter Gotye.
He's created a mash-up from YouTube covers of his hit.  It really is a beautiful love letter back to his fans. Have a watch... it's truly engrossing and fascinating...
