If you look at the kind of budget political parties have allocated for e-campaigns, it is substantial to create a whole new model of business, around this concept. Just think of it, right from leaders of known stature like Advani, Murli Manohar Joshi, to smaller not so known leaders, have their own blogs to promote their ideas. These blogs are being written and maintained by group of professionals, who are getting due remuneration for it.
In times to come this trend will continue and scale up in magnitude. In India there are innumerable tech geeks, Internet aficionados, who have great mastery over blog creation, writing, social media usage, who can surely utilize their skills to promote political parties and individuals in a focused manner.
There could be a cohesive business model around Internet consultancy or use of Internet to promote parties and ideas. In terms of investments all one would need would be time, broadband connection and access to free blog creation (which is there in 100's).
I feel, in this time of downturn, people should explore this business model and who knows, in times to come we might have an Indian Google or Yahoo of political campaign creation and promotion.
