Being from the social-digital industry I have seen it really take off over the last few years.While more & more people & corporates are talking about it Yet the noise & the questions around 'ROI of Social Media' have also increased.Considering that some of the best minds of the marketing-brand building fraternity are involved with the medium & a lot of them for some time,why the question & debates remain is in itself quite a dichotomy!

ps-Forgive the language,a pure attention grabbing headline but I think in this scenario makes sense :-)
