Choosing your @ name can be a challenge, particularly these days when a lot of names are already taken.
Regardless, it’s still important to choose something that is both memorable and relevant. It’s best to choose something that leaves no doubt what it says. Make sure is doesn’t contain too many confusing or unnecessary characters.
Your aim should be to ingrain your name into people’s heads. So, avoid changing your handle (only do this if you’re going through a full re-brand).
