Social media is an Internet phenomena. Virtually anyone over the age of 13 can join sites like Facebook and MySpace, where they can interact online with a group of friends. Twitter lets people offer commentary on anything and everything - and can be a source of new trends and stories long before offline media provides any information. President Obama has a twitter account, and so do I. Social media is one of the means that create a global community. Fun, friendly, and, unfortunately, a vast pool of information for phishers. There is a new awareness of how easy it is for others to get private information that you and your friends provide.
Businesses are also trying to utilize social media to create a different sort of awareness of what they offer. The Mexican restaurant down the road from me has a Facebook page, and occasionally offers specials to readers who appear on their doorstep. It is also perceived as a tool that can help SEO (search engine optimization) by creating awareness of available content. Social media, like the global community it is part of, is still evolving.
