[JayNasty]

When sone writes a tweet ex: (tweet here) >>>>>>, what do the arrows mean?

[Vamp]

The arrows are used in two ways.

Firstly to express approval or liking.

dog>cat. Dogs are better than cats. I like dogs better than cats.

dog> I like dogs

< indicates disapproval

The number of arrows indicates the strength of feeling

dog>>>>>> I like dogs very much


Secondly they are used as arrows to draw attention to something felt to be important
