I think the key problem with this post was, although it does mention "This idea is the foundation of Augur's event resolution mechanism (as well as that of Truthcoin, Augur's theoretical inspiration)." along with a link, the blog post itself didn't mention a key aspect of Truthcoin. Which is it didn't really go into the reputation system and how you can have varying amounts of it, but the total amount is fixed.
Sure, the blog post mentions weighting reputation, but if I had never read about this project before I think it's pretty reasonable to assume I wouldn't have made the connection.
In my interactions with the community I find myself talking about what you've already written the most (I never talk for only a Truthcoin audience).
I didn't write that post, and it was mostly well received minus that slight confusion above. What seems to work best is explaining enough of Truthcoin so that the audience can understand what you're talking about, still mention the Truthcoin proposal (whilst not assuming they're familiar with it, at ~40 pages or so it's a lot to assume people have read through), and then lightly touching on value-added. It is difficult to navigate
