If I had to pick one factor that was responsible for most conflicts — I would choose miscommunication.
Why? Because miscommunication can create other factors that may lead to conflict.

It happens when one side doesn’t communicate enough information to us, or we misinterpret the real meaning of their words.
This is a becoming a common problem now-a-days because social networking relys so heavily on type-based communication which is ‘asynchronous communication’, meaning that people do not communicate in real time.
Type-based communication does not allow for an immediate feedback response, so our minds have to interpret what the other person is saying based upon their typed words alone.

The delay in response, as well as other factors such as spelling and incorrect use of grammar or punctuation, can greatly increase the chances of miscommunication.
Not to mention that tools such as twitter, plurk & facebook require users to be succinct in what they type. This can suck out any intended meaning or remove other context that will clarify what is meant.

I have been victim to both misinterpreting what was typed & the context in which it was intended, as well as having others read a totally different meaning into what I had posted.
I am sure I am not alone in this.

Like this one time, I thought that @aplusk actually wanted me to follow him because he understood what twitter was all about……..
