Hi Denise,
I like your idea of using HIVE to create a brainstorming community to inspire creativity and innovation in your department. I would think it beneficial to (eventually) include as many stakeholders as you can, including of course the students themselves. Maybe you could start out by holding a dedicated online focus group and expand out from there. I have tried similar ideas with dedicated learning communities on public forums like the now defunct Google Plus (which was taken down due to security concerns). But, as Dr. Rodney pointed out, the fact that the information resulting from these conversations would be securely owned by the group, and controlled by you, is certainly the benefit of a social media platform built on DLT, like HIVE. I also think your idea of promoting input via the platform's token system is a smart way of leveraging these tools to promote collaboration, participation and engagement.
