Digital branding is still a relatively new practice, and a lot of information about what should and should not be done is still emerging.
For some people and some industries, having a digital brand that transfers from a meeting in person all the way back to every tweet they send can be immensely powerful. For others, it’s potentially unnecessary.
The best way to answer this question for yourself is to study the people that you are trying to influence, and do some testing.
Research, test, optimize.
