“Exhibitionism” is an interesting way to put it. I myself vary in my personal online presence and my professional online presence. While I am very unlikely to ever his the status update button on Facebook, I will put serious thought and effort into a blog post, linked in profile, or tweet. I have been working in extension related research for a few years now and I am beginning to see social networking as a valuable tool in extension. At some point sharing research and findings can be made considerably more easy without looking like self-promotion. That is at least my goal when I post, but that could be skewed by the very applied nature of my research. Credibility is definitely a concern in social media. I do think that the informative value or the connection necessary for communication to be successful, can be damaged by poor grammar and misspellings. That is true for all communication. I hope that members of our research community can find a way to synthesize their research that can be readily accessible and perhaps combat some of the inappropriate popular science blogs that are loosely based on science. If we do not confront these very loud but incorrect voices, our stakeholders will be left to assume that writers like the “Food Babe” are adequately informed. Concerns of self-promotion and self-grandizing are probably a good sign of humility at this point! Good luck!
