Assuming you are a marketing specialist in the company you currently work with (for real), and you were asked to investigate how the company should use online social network to improve its business. Given the limited budget, the company will select only one service provider. Can you select a popular social network site (Facebook, Twitter, etc) to investigate the following aspects

- Profile of the site, such as size of user base, key features, advertisement product profile (both web & mobile based)

- Demographics of existing advertisement clients, and their success (or failure) stories

- Your company's existing channels to out-reach customers.

- Any companies in the same of similar business as yours are using social network in their marketing effort.

- Recommendation about marketing product selection and projected cost.

- Potential downside, or any other issues related to this online social network based customer out-reach.

- Another other issues related to the decision your company is to make about this social network initiative.

Here are some sketch notes from my recent reading on Facebook IPO.
