What do these <> mean on facebook and twitter.?

[Els]

Like people put a list of things or two things then these arrows. Example:
Justin Bieber > One direction
or Demi Lovato > Michelle Keegan
or Eastenders > Coronation street
Like, what do they mean?
Thank you. Also what does this mean:
The Wanted >>>>>> 😍

You know in maths where they'd say like, 0<5 means 0 is smaller than 5
so on twitter/fb they mean the same, for example

Justin Bieber > One direction

means

Justin is better than One D

[James]

Justin Bieber > One Direction = They like Justin Bieber more than One direction

[Chris]

Think of the arrow as a mouth, eating the bigger or greater thing. In the example you posted, te first person is sayin that Justin Beiber is better than One Direction.

> Is more than
< Is less than


So for example; Justin Bieber > One direction
would mean you prefer Justin Bieber

[Mysterious]

They mean the same as in maths.
So, Justin Bieber is better than One direction.
Demi Lovato is better than Michelle Keegan
Eastenders is better than Coronation street.

these signs are used in maths so it's as though instead of saying 1>0 (one is greater than 0) it's as though Justin is better than One Direction like my life is > than yours is the same as my life is better than yours! x
and the wanted >>>>>> means the wanted are amazing!
