Q: How is the technique different to the traditional note taking?

In traditional note taking you try to write down a close copy of the information you are listening , but in sketchnoting you have to make a visualization of this concept and then drawing it, making it easier to assimilate and easier to be remembered, because you have to use your own graphic language.

Q: How does this visual approach facilitate communication of your ideas? Conversely, how does it prevent it?

Sketching it’s a great way of interact and show your ideas to other people, a good sketch can overpass the language barriers and can explain abstract concepts in seconds, on the other hand it can be very confusing if the illustrations are not simple or iconic because they will giving room for personal interpretations.

Q: Personal challenges as a sketchnoter.

Speed, and clarity ;you have to be able to synthesize lots of information in short time and transform it in icons or other universal symbols for the people to understand your notes.
