i don't quite understand how BBR's involvement in it is supposed to bring up the value. is that discussed in the thread? i might also just be failing to understand something fundamental about what superNET is and does... @_@
i've scanned through the original post in that thread several times, read some news articles and a bit of the prospectus and still don't think i really get where each (any) coin fits into the network. economics is not my strong suit at all and it seems like most of the documentation takes for granted familiarity with a whole slew of concepts in order to accept its premise.
is there no FAQ or such like for simpletons like me?

For people who want full anonymity right down to the network level Teleport(network level anonymity) and BBR(unlinkable inputs and outputs) is the solution. And the only way to use those two technologies together is via SuperNET. So BBR is a critical piece of the privacy puzzle.
And SuperNET itself is a massive project to increase adoption of currencies. In fact ~$100k was just budgeted for marketing to start off 2015. BBR being a core part of SuperNET is a big deal. I myself am working on a SuperNET related project that will target real world use and I hope to be able to include BBR in my plans as well.
SuperNET intends to grow a large user base and as a result of that BBR should gain users as well since it is quite good itself.
