faut-il préférer Twitter à Facebook pour organiser un jeu-concours ? Depuis quelques semaines, Facebook a mis en place de nouvelles règles encadrant l’organisation des concours sur sa plateforme (voir ici l’excellent article écrit par @Kriisiis sur le sujet). Il n’est désormais plus possible d’organiser un jeu concours pour augmenter directement (par le système du “like” obligatoire pour participer au jeu concours) la taille de sa communauté de fans sur sa page Facebook. “Facebook ne permet plus d’agrandir sa communauté de fans par le biais d’un jeu-concours” Désormais, il n’est plus seulement possible que de créer un jeu concours par l’intermédiaire d’une application n’ayant aucun lien avec la page Fan. Ces nouvelles règles ne permettent plus d’augmenter sensiblement la taille de la communauté. (Mais faut-il privilégier la quantité à la qualité de la relation avec ses fans ? “Une liberté d’action très importante sur Twitter” Twitter est au contraire très souple en ce qui concerne l’organisation des concours sur sa plateforme. Et vous, qu’en pensez-vous ?

Are stock prices affected by social media? - FTSE Global Markets According to a survey of 360 UK financial professionals carried out by Colt Technology Services, social media sites such as Twitter and Facebook are affecting share price volatility. The research found that 63% of respondents, including brokers and heads of trading desks, believe the valuation of individual stocks can be directly linked to public sentiment contained in social media channels. While only 7% of respondents regard social media sentiment as an important indicator, just under half (45%) of respondents regard it as a trailing indicator, demonstrating that social media definitely has a role to play. Firms such as hedge funds and proprietary trading houses are now able to scan social media data at random and then categorise messages into one of a range of public mood states. The firms then use algorithmic or high frequency trading strategies to place trade orders, enabling them to potentially steal a march on competitors who trade using more traditional forms of data.

My Homepage Storytelling with Data Feb. 28, 2013 This is a condensed version of my opening keynote at the Tapestry Conference, which was held yesterday in Nashville’s beautiful Union Station Hotel. I’m writing this from memory so at best it will only be an approximation of what I said. Thanks to all the organizers and attendees for a great event. Update: a video of my talk is now available on the Tapestry blog. Storytelling with data I was happy to see that the theme of this conference was storytelling, because as we develop new ways of gathering, processing, visualizing and presenting data, we sometimes risk focusing so much on techniques that we forget to tell stories. Storytelling is a basic human activity. Have an audience We naturally adjust our stories to fit our audience, but with graphics we don’t have that luxury. So whenever I look at a data set or try to build a graphic, I need to know who my audience is. I work at The New York Times, so the question is: Who is my audience?
