Now to OPs question depends on how active I m here ... Once I even saw close to 3 digit numbers in alerts / notifications...not anymore
I thought it was the color white, refering to whether a person is wearing a white dothi<vetti?> or a non-white, like a sarong or lungi. And the post was referring to whether what was liked/quoted/etc/ was "clean" (lily white, snow white etc..) or not. Quotes "alert" me the most. My max was 5.
hahaha...no wonder I thought vela-vetti is a white-dhoti, a metaphorical reference to clean-posts....as in a genuine-post that was needed, because googling came up with zilch.
'Vela' means job in Tamil, while 'vetti' means jobless. "No vela-vetti or what" is slang for someone goofing off.
