This could be harmful when you are trying to move something heavy and it doesn't move.
You walk and that is the example of friction
Blue cheese is a non-example of friction.
A example of friction is rubbing your hands together the heat you feel is friction. Oh dont be a shat head.
Sliding your hands together is an example of sliding friction.

The question is Why is internet useful? not why internet is unuseful. I cant find the exact answer if the internet is unuseful to you.
this answer was decided that it was unuseful and you should look at another answer.
Whenever you were trying to reach high speeds or conduct exact experiments where friction would slow something down or cause heat. For example, friction is extreamly "unuseful" when spaceshuttles are re-entering the atmosphere because the friction of the spacecraft and the air create incredibly height temperatures. Special heat plates were invented to absorb this heat. If they fail, like in the re-entry of the Columbia Space Shuttle, the shuttle will be completely destroyed.

An example of fluid friction is the air resistance felt by an airplane.
