With Earth Day fast approaching, our latest influencer analysis followed green buzz in the blogosphere. Check out the full story in PRWeek's Media Watch column.

Here are a few quick highlights:

- When looking at the topic of “going green” who knows better than mom? Four of the top 10 influential blogs pertaining to going green are written by mother's groups: Boston Mamas, Chicago Moms, Blog that Mommy, and Motherproof. Mothers have picked up the green cause like wildfire, and are discussing all kinds of green topics from food to cleaning.

- If you don't have plans yet to celebrate our planet, look to the blogosphere for a host of ideas. Influential bloggers have latched on to green ideas and Earth Day celebrations. Approximately 50% of the influencers have posted information on fund-raisers and special events that will take place around April 22. More than 70% of the influencers discussed Earth Hour, an International campaign that took place last month.

- Another popular topic among the Earth Day and green influencers is the cost of “going green.” Costs for green infrastructure – especially in homes – can be prohibitive, and organic food is often expensive. More than two-thirds of the influential bloggers have offered tips on how to go green without breaking the bank.
