Positive for a change and well done :
http://www.forbes.com/sites/investopedia/2013/08/01/how-bitcoin-works/When talking about how to use there is no mention of mind wallets.
Still don't get it though :
"Why does transaction verification or confirmation take so long? Because the complex algorithms involved in Bitcoin mining"
"The concepts of cryptocurrencies in general are abstruse and abstract."
I would argue that at a "concept" level this should not be the case, the "concept" is not that hard. So many seem to be turned of by the idea that it is "abstruse", "abstract", "technical" etc.
