In this fast pace world, it is common for us to shorten our sentences with acronyms and short forms. The following is an example of how short form can lead to communication breakdown:

A simple short cut of spelling "didn't" led to a series of misunderstandings. Short forms are supposed to make it easier and faster for us to convey messages, yet in this case, it caused misunderstanding and made it more troublesome because someone else has to explain it clearly. This is a not a big problem because it is just casual chatting on Facebook. However, if the setting and context is set in an office or work email, it may cause a lot of unnecessary trouble. Thus, nowadays I avoid using short forms as much as I can to prevent miscommunication.
I believe no matter what kind of jobs you take next time, you have to communicate with people, be it your subordinates, peers or superiors. Therefore, we have to know how to communicate appropriately with the different groups of people using different tone, different channels, etc. Because without good communication skills, I doubt one can climb the social ladder. A degree (i.e. IQ) can only get you the job, but it's the people and communication skills (i.e. EQ) which gets you promoted. :)
