An essential part of marketing conversation is being who you are. Moreover, best practices indicate that you should be open and honest about your identity. Resist the temptation to base your online identity what you want to be or some ideal form. Being accessible, approachable, and human is the best bet.
Honestly, folks are paying pretty close attention to your voice, tone, and message and so it is just safer to use your own voice and tone, uniquely tailored to your target community.
Whether you decide to wear your affiliations and intent on your sleeve or not, one thing is essential: authenticity. Outreach is more effective when you are being conversational, casual, and allowing your passion and excitement to flow.
