As I've mentioned in previous posts, I'm currently spending most of my time focused on services to help local offline businesses get results online through video marketing. I've worked online for a number of years, but as I look for new ways to get the word out for my clients, it still amazes me how vast the Internet is.
Here's a social networking tool I found out about from marketing expert John Jantsch. It's a free facebook app for friends to share online referrals for their favorite local businesses. It also helps the businesses ask their customers to promote them.

P.S. I'm not an affiliate of the site. I just like to pass along useful things when I discover them.
