Yes, we seldom use "hello" except when answering the phone, even then if you have one of them caller id things and know who you're going to be talking to it's "hey". "Hi" hardly is ever used. Just at fancy parties and such when you're talking to people who wear French-cuffs and lift their pinkies while drinking "beverages". They might take your "hey" as somehow making them common.
But for us regular folks, "hey" is the accepted greeting. Probably more than you wanted to know, but, hey, thanks for the warm welcome.
