Meh, I think it's fine for blog posts to assume familiarity like this if it reflects their niche. They're writing for the type of person who already knows what Duet is. It's not the NYT where there's a massive general audience.
In fact, the choice not to explain things tells me a lot about the shared knowledge of a niche when I'm looking in from the outside. I don't mind the extra digging to decode it and the implied familiarity gives me information about its importance.
