I found out on the web this presentation.
What shall we think about it? I believe that it shows that social media remains a new medium. And therefore a lot of people are still figuring out how to do. I can't blame managers which don't really know how to handle those media, and especially what to expect.
I believe that there are a lot of progress that happened. New statistics came in, new marketing success came up, and I believe that we are starting to have a good outlook of what the future will be for social media.
