Diving and the diving-suit
• Using the example of
diving and the use of
the diving-suit. In the
past, the diving suits
were limited in use,
because of the weight
and permanent
connection to the
source of air.
Why is it important?

that 60% of the time
people are not able to
find the information
they are looking for on
the Web sites.
Jakob Nielson

• Is considered to be the
smartest person on the web.
