I had a client who loved Speed Racer. He knew everything there was to know about Speed Racer and could tell you about it the way others might tell you the chapter and verse of the Bible. This person was an undisputable Speed Racer expert, but how does he let people know that? The Internet gives this person as well as others an opportunity to share their expertise with tools like blogs, social networking sites, email newsletters, Wikipedia, and the rapid creation of new websites.
Social Networking
Websites that connect people online based on existing friendships/relationships, similar interests, creative communities or for businesses networking. Examples include Facebook, LinkedIn, You Tube, and countless others. Social networks encourage open interaction about any topic including reviews of companies, sharing pictures and videos, answering questions (on any topic) and keeping lines of communication. Social networks expose the connections that others have to the people they are connected to. This You Tube video explains much of social networking very well.
Network
A sphere of influence in Facebook. There are networks for cities, countries, schools and large companies. Networks are one layer in determining if you can see information on a users profile without being their friend.
Blog
A web site designed to share information that is updated often. A blog is often used like a journal to share thoughts and feelings on issues or on happenings in a company or organization. Blogs can be silly and not have much value but they can also be a key advertising and marketing technique.
