Furthermore, a good part of the reason people want to avoid using centralized exchanges is due to privacy concerns, and given that the trail is completely transparent on bitshares.......

No, I stand by my assertion that the biggest use for the platform was to act as a stablecoin bank. And without stealth, it's never taking off.
Would you use your bank if anyone in the world could check your balance online?
Me neither. Nor would 99.999% of the people.
Anonymity comes from "how" you obtain BTS to transfer in, and "how" you exit BTS, by gatewaying it out.
You shouldn't need anonymity within the Dex itself.
I really don't think that's the problem.
I think the problem is soley limited to:
a) Ease of Use
b) Popularity (you need to use the Dex because everyone else is using the Dex scenario, just like facebook)
c) Education and Advertising as an ongoing effort.
The DAC and DAO, and DEX, all have one fatal flaw. There's nothing in its design that encourages ongoing promotion of itself.
This is why large corporations (even Coke and Pepsi) to this day, spend gazillions promoting themselves. Do you think if Coke & Pepsi stopped advertising they would lose market share? They're industry leaders already. Yet they don't chance it.

Sure, someone could make an offer to do promotion in exchange for payment. But this is a tragedy of the commons problem. No one wants to spend BTS on something that may not yield a return, so they wait for "the other guy" to do it. Problem is, we're all "the other guy", and none of us is doing it either.
BitShares as a Dex is a tool that is hoping to go viral without any significant adoption plan. You don't create a tool hoping smart people will discover the tool. If that was the case, the next infomercial on TV showing the latest gadget would be non-existent. They'd simply create a new gadget, put it on store shelves, and "hope" that smart people would discover it in the store, or go by word of mouth.
Word of mouth, and smart people, are very limited ways of growing adoption, and are doomed to fail.
As soon as we realize this problem, perhaps we can fix it.
(Oh, and everytime we get a little "blurb" somewhere in an online article, that is nothing to throw a party about. That's the very minimal of what we really require)
