If the subject of social media in the financial industry interests you, then this is the best one out there. There are few people who can match Christophe’s intellect, experience and passion for social channels in finance. He’s also extremely gracious and polite, even when he offers criticism — you can tell he’s a pleasant and affable Frenchman. Christophe’s blog posts are frequently built around case studies. He could be looking at the Twitter activity of a major European insurer one day, then the Facebook page from a U.S. bank the next. You never know exactly what he’ll be covering next, but you can always count on reading a fair analysis of social initiatives from financial institutions only.
