Yes, because exactly what we need now is a needless tag seen on the end of every post. This is a forum, and while I'm pretty open to branching out in the more conventional "social media" direction, there's actually no point in adding every feature the sites use. Nobody cares if when you post about your favourite Pokémon or toilet brush, if it comes from your phone, your computer or otherwise. It's needless clutter.
