Most of us are working for corporate houses and we understand the significance of communication (especially for geographically disperse locations) and email etiquettes. Over recent past, I observed that many of these communications across peers are done through IM's. There are pros and cons to the chat communication that is prevailing now.
1. Quick turn around time
2. Grabs immediate attention of the receiver and sender is deemed to get a response/acknowledgment
1. Becomes a lot more unofficial
2. No archiving - means you loose the proof
3. No means of intimating the people in higher ladder (Unable to CC).
So which way is better and which will prevail over the longer time frame?
