where can i find information on how firefox use each social media (twitter, flickr, youtube, facebook)?
I'm doing a report on Mozilla Firefox with YouTube as it's social media. I'm finding it hard to find information on how Firefox use YouTube and how YouTube help to market Firefox. I realize that maybe YouTube posts are probably more likely to be instructional, whereas twitter posts will be more promotional. However since this is a report, I must find reference to support what I write. I'd also like to include information on the age range market target of Firefox and each of the social media that it uses (Twitter, Facebook, Flickr, YouTube). I can find age range on Twitter and Facebook user but they are not specifically on Firefox user.
Can I get suggestion on where to find these information?
