I am pink right now from blushing back and forth. You are helping my blood flow today. Thanks. (And I will make u coffee or something...)

It is a great social networking tool to learn about industry trends. Pay attention to the forum and blog section - you will find something that interests u. A lot of talk about use of social media in recruiting, good posts about sourcing, and best recruiting practices.
You will also find info about paid and free webinars/ chat classes, etc.
