No matter what your field is, you are likely behind the competition if you don't blog, use Twitter, LinkedIn, Facebook, or YouTube. This video helped me understand the basics of computing online today.

Lesson #2: Talk the talk
A major part of social media involves understanding the translation of online jargon. Many sites use symbols as part of their language. A good example is Twitter which uses symbols like @, # or RT to direct the conversation to the rightful receiver. Using the language equation appropriately is important because a conversation is meaningless unless the receiver understands. There is no leeway for faking it; technically, it is a right or wrong, black or white situation and if you don't know it, it shows.
Lesson #3: Walk the walk
Engaging online everyday ensures an effective online presence. The tempo of the time has sped up and online networking is no different. As quickly as the news arrives it passes, and we're on to the next story. The online parlay via social media is a flash flood you don't want to miss. Make it part of your routine every day.
Lesson #4: Contribute meaningfully
News moves rapidly. You have a fleeting window of opportunity to take part in its analysis. Instead of superfluously acknowledging what's already being talked about, accrue to information with a unique angle. Adding your brilliant interpretation initiates additional arteries of discussion. This is meaningful social media.
Finally, meaningful contribution needs support. Ensure your opinions surround relevant sources of information. The source of your input is as pertinent as the input itself.
