Extra applause for wit!

What does it mean? What is the "wit"? Extra applause from whom? I'm really confused.

Answer

The 'wit' is clever humour.
The 'extra applause' is additional praise.

So you will get additional praise from your tutors or fellow students if your tweet is funny.

Answer

'Wit' means humour, something amusing or funny.

Answer

If your report, or tweet, is written with humour, we shall give you a higher mark.
