We often overestimate the importance of new methods of contacting possible business partners or customers such as LinkeIn and ignore traditional methods of drumming up business and business networking.
I saw a perfect example of traditional methods of contacting possible business partners in this article on Google News - "Doing business in Gurgaon... the Chinese way" from India Today.
Enterprising Chinese business men are paying women to hand out their business cards outside an Indian Mall urging people to do business with China.
If you are interested these women will guide you to a coffee shop where tables are occupied by business men looking to convince Indian people about their business ventures.
Sometimes the simplest of ideas can generate the required amount of interest.
