What does ">>>>>" mean on twitter?

[akjfklsa]

for example if someone puts someone's name then >>>>>
what does that mean ?!?!?
but they didn't say anything else after >>>>>>

[Femme fatale]

It means it's directed to that person

[karli]

it means thumbs up and <<<<<< means thumbs down

[ReyRey]

When someone puts ">" it means greater than. And less than is "<".

Example:
If you like texting you would put: TEXTING >

If you don't like texting you would put TEXTING <
