I'm pretty new at alt coins and the technical aspects. I've read several posts about the SBC mixing service without really understanding what the concept for the end-users is behind the technical description.

There must be probably a good mid/high-level explanation somewhere (without falling too much into marketing), I would be happy to read it ! Otherwise, it will be necessary to offer a good user-level description of the service as it looks like being a great benefit for the popularity of the coin.
