Definitely over used, to the extreme. I have pondered this myself.
Funny thing is, (a) I am guilty of following this trope as well and (b) I have yet to see a good portfolio that doesn't start this way. It's almost as if using this wording means you have graduated to a certain level of skill lol...
I tried to switch mine up a little though, by having my "Hi / Hello" iterate through different translations (Hola, Bonjour, etc..)
Same shit, different languages :)
