What is Social networking?

In my opinion, Social networking is a sort of body that consists of lots of magic rings, which is called a node in a computer language. The magic rings can be easily connected to each other in the cyberspace according to their interests such as ideas, hobbies, friends, relationship and the like; therefore, it could be a useful tool in this fast-moving society.

Now, social networking is getting popular. I think that facebook.com and myspace.com are good examples. From the two, people can get familiar with the term social networking. They also know what the social networking is for. Maybe, some people misunderstand that is all about the social networking. In fact, the merits that we can get from it could be way beyond our imagination.

I think social networking could be a useful tool in E-Marketing.
Let’s take facebook.com as an example.
One of your friends commented favorably on new MP3 on your blog. It will affect a purchasing decision of other friends. It can be called word-of- mouth marketing. In the E-marketing, the power of the word –of-mouth can not be ignored.

Why am I here?

E-Marketing is growing very fast because of the proliferation of internet. but, I am not that familiar with the term of E-Marketing. Therefore, taking E-markting course (Host 4103) this semester will be a chance of better understanding E-Marketing.
I want to know the following three at least.
First, the basic information on E-Marketing.
Second, the Limitations of E-Marketing and Security concerns
Last, effects on hospitality industry.
When I know the E-Marketing inside out, my future will be brighter and shining.
