If one studies history of automobiles, the first cars powered by internal combustion engines running on fuel gas appeared as early as 1806. But early autos were little more than horse drawn carriage fitted with an engine. It was not until 1889 that Gottlieb Daimler and Wilhelm Maybach designed a vehicle from scratch to be an automobile, rather than a horse-drawn carriage fitted with an engine (for more on history of the automobile, see this link).
Something similar is happening with respect to Social Networking technology today when it comes to Customer Relationship Management (CRM). Instead of modifying and re-engineering their CRM business processes to take advantage of unique characteristics of Social Networks, companies are fitting “Social” engine to their existing CRM carriage and are expecting great results from it.
