Ever since I’ve been participating in the Twitter arena, I’ve seen numerous questions (tweets) from corporate marketing teams, agencies, and business owners about how to leverage Twitter for your business.

So I’m reading through my news headlines today and I see 20+ stories about Dell (@DellOutlet) offering exclusive deals to their Twitter followers. Here is a story on CNET today entitled, “Dell cozies up to its Twitter followers.”

I think this is a great example showing how B2C companies can really benefit and leverage Twitter for actual sales and customer interaction. My only slam on Dell is they aren’t following customers back which means they are stuck in a one-way dialog…which isn’t ideal for the customer. Nonetheless, they see value in this channel if for no other reason but to offer great deals to consumers.

Other great examples of companies using Twitter for the good include:

Zappos – @Zappos - This is actually Zappos CEO…great move!

Comcast – @ComcastCares - Frank responds to upset customers faster than their customer service line…

Whole Foods – @WholeFoods – Very active and following almost 42K on Twitter…

I would love to hear other great examples of companies effectively using Twitter & to get your feedback and thoughts on this subject.  Thanks!
