Chevrolet and Microsoft Advertising (where I work) have created a great example of putting technology and social media to work together for a marketing campaign.

The highlights for me include:

1. Tech: The site has a nice design with integrated video as the primary content type
2. Social: The goal is to share videos you like with a leaderboard of top sharers
3. Marketing: The site is for GM’s Chevrolet brand and the winning video could end up being shown on NBC during the Super Bowl
