I wrote a diary about "Linkedin" in my class
and introduced it to my teacher , Rose.
Please read and check it my diary ：）
Linkedin is a kind of social networking. It is much different from
other social networking - Twitter, facebook, Google+ and friendster.
So, it is social networking for business and is used to connect
companies and applicants online. That is, it's matching service
for business. So applicants(users) will write (add) necessary information
- Education, Connections, Career and Interests on online resume.
And then, companies will check it and send e-mail to applicants.
