@ZipLine-- I think it's a great idea to use social media sites. It allows the manufacturer and the salesman to instantly connect with consumers.
For example, when a new product is launched, a manufacturer can use these sites to get instant feedback from consumers. It's also a great way to advertise products. I know quite a few brands who market new products by holding giveaways on these social media sites. It's a brilliant idea and it works extremely well.
