You do you. But it may have an impact on people looking at your profile. As people in this thread write. But on the other hand you might also attract the attention of someone who is more on the same wavelength as you. It’s up to you to weigh the pros and cons. Do you want to fit in with the inexpressive, professional corporate tone, or do you want to add a bit of color? You can’t please everyone anyway, but it might serve your interests to conform to the expectations of people you DO want to please.
