Hitwise has come up with some interesting stats on where people are searching if they are concerned about the environment.

A lot of searching is taking place on Wikipedia, which shows how much people trust it. Government sites are high as well.

Getting people to come to you if you are a key player in the environmental market might mean looking to join up with these sites, or looking at their content to see what you can learn from it.

More unbelievable stats out on Facebook. According to Hitwise, Facebook accounts for more page views in the UK now than Google Uk, eBay UK and YouTube combined.

It’s worth looking closely at the numbers, which, from a brand/company perspective, underline the importance of having a good Facebook presence, or at least being aware of what people are saying about you on Facebook.

It’s no secret that I admire the work of Jeff Jarvis. His book What Would Google Do? is a fascinating insight into the impact that Google is having on our culture and the ways we do business.

John Gapper from the FT has criticised his book. Rather than being like Google, businesses should be like Apple, Gapper says.

Jarvis has countered Gapper saying he has an ‘old media mindset’ which is bent on control.

Here’s Gapper’s review.
