"Meet off" vs "meet on"

I recently came across an article which read: A guy I met off LinkedIn who is a lawyer explained to me...

It could also have been "A guy I met on LinkedIn who is a lawyer..."

Can someone explain the difference between these two and when to use them.


Solution 1:

Both are grammatical, but the latter is more common and accepted as the standard phrase. But again, MW defines off of, so it's really a question of using it on audience that you think can assimilate the usage.
