Happy Friday! There's a tradition on Twitter (if such a thing exists on Twitter) for people to share other great people to follow with their list of followers. Every tweeted recommendation comes tagged with #FollowFriday, it's a great way to find great Twitterers.

Here a few great green Twitters who I follow who you should add to your list.

OliviaZaleski is host of CNN Money's Business of Green and a great Twitterer. She uses her account to interact with her audience and often solicits questions for the big wig business people she interviews.

Ecorazzi is the Twitter account for the web's most popular green celebrity site.

GreenGirls is Apple Levy, founder and head of Green Girls, an LA based site focused on sustainable living for women.

CarbonHound is my pal Ted Rose, a green energy entrepreneur and ex-radio journalist. He's super smart and covers developments in the renewable energy world.

RShreeves is Robin Shreeves, one of my fellow MNN bloggers and a freelance writer and eco-mom extraordinaire

MotherNatureNet is MNN.com, the best green website in existance, and I'm not just saying that because it's where I work. Ok, maybe just a little, but we are a hell of a great site and MNN's Twitter account is no exception to that.

GreenDig is another great MNN blogger Karl Burkart, green tech and social media wizard, podcaster, and proprietor of Green Dig, a great site to find green news around the web.

EcoChickie is my friend Starre Vartan, the brains behind Eco-Chick, one of the best green womens sites around.

MaxGladwell is the Twitter face of Max Gladwell, a site that covers the convergence of green and social media. Max Gladwell came up with the idea of #EcoMonday and is a great account to follow.

I wouldn't be a shameless self promoter if I didn't throw my own hat into the ring, you should follow me @sheagunther.

And don't forget #EcoMonday, the specifically green version of #FollowFriday. It was kicked off here a couple of months ago with the Great Green Twitter Follow Parade, another awesome place to track down green Twitterers. I also highly recommend visiting the list of people that @EcoMonday follows, they're all people who have been mentioned in an #EcoMonday tweet and thus are highly likely to fall solidly on the greener side of life.

Happy hunting.

Shea Gunther is a podcaster, writer, and entrepreneur living in Portland, Maine. He hosts the popular podcast "Marijuana Today Daily" and was a founder of Renewable Choice Energy, the country's leading provider of wind credits and Green Options. He plays a lot of ultimate frisbee and loves bad jokes.
