Good question. Let me start my answer with a broad statement…
I believe that Super Users need to be given a certain level of “velvet rope” experience. They may not get their own room at the club, but they certainly get a velvet rope around a table with “Reserved for Super User” on it.
One of the non-tangible incentives for being in the super user program is that they get recognition, including that of the public variety. That means, yes, I typically think about how to call them out publicly. This can include:
- Home page reference
- References on the super user info page outside of the community
- Pinned posts
- Badging (that specifically calls out their level, perhaps in a more unique way than most badges)
What you decide to do is highly dependent on your culture, community, and industry.
I would also consider “portability” as part of this same question. How easy is it to showcase their status/title? Microsoft MVPs, for instance, are able (and highly encouraged) to use their MVP status on resumes, LinkedIn profiles, and email footers. This not only helps elevate the individual MVP’s status in the world, but also helps promote the value of the program. Make them feel, and give them reasons to feel like their participation is something that helps them build their own personal, emotional, professional identity!
You didn’t specifically ask, but I also believe your question includes the thoughts of “what other benefits do they get”. One of which is likely the ability for them to talk amongst themselves without the rest of the community getting access.
