So since you felt the need to quote me from 2 years ago here is a new quote.

Millies, mBTC, mikes, uBTC have been proven to be horrible.  They are cludgy and nerdy and the chance of mainstream adoption is essentially zil.  Nothing has really happened after a couple years of pushing it. 

Bits is the only thing which has shown any momentum at all.  If BitPay starts using it, we will as well, hopefully others will and I have faith humans who can conceptualize a decentralized peer to peer currency system will be able to figure out bits.  "Bits" is a good colloquial for uBTC.  The idea that people won't be able to figure it out is just silly.  "That will be 22 bits please", short, simple, easy.  It still provides two decimal places which means easy integration into legacy accounting software.  We use uBTC internally for this exact reason.  Many accounting software packages can't handle the exchange rates or precision required to use either BTC or satoshis.
