Ok, I’ve been heads down on projects all week. However, here are a few tidbits worth noting from the influencer relations world.

Philippe Winthrop, one of my favorite enterprise mobility analysts leaves Strategy Analytics today. You can continue following his adventures at his Enterprise Mobility blog.

Jon Collins, MD and CEO of Freeform Dynamics, is raising funds for Water Aid by running in the Brighton Marathon. More at his Nothing to Declare blog and at JustGiving.

And, if you sometimes doublecheck links to see whether you’re reading about Jon Collins or Jonathan Collins, well, you’re not alone. Just sayin’.

The 2010 Edelman Trust Barometer has raised all sorts of discussion with its findings like this: Trust in social media and mainstream media has dropped like boat anchors, while trust in CEOs has risen. Tech is the most trusted sector. Trust in financial analysts remains high despite their failure to predict/reveal risks big enough to sink nations. Freely available.

Expect to see this latest Edelman Trust Barometer cited as heavily as usual in analyst relations circles. Once again, it puts industry analyst reports (Gartner et al) and business magazine articles as the top most credible, most trusted source of information about companies.

Social media took another big hit this week with findings from a Pew Internet & American Life study on social media and mobile internet use among teens. Blogging has declined sharply among teens and adults under 30. From the summary, “As the tools and technology embedded in social networking websites change, and use of the sites continues to grow, youth may be exchanging ‘macro-blogging’ for micro-blogging with status updates.” Freely available.

Davos is a crucible of influence and influencer relations. My favorite quote this year is from Larry Summers, U.S. presidential advisor: the U.S. is experiencing “a statistical recovery and a human recession” (hat tip WSJ).
