Actually this thread is composed of a greater than normal amount of people who actually have at least the foggiest idea of what currency is.

Most internet rhetoric you see about bitcoin takes a very pop-culture POV - the same people who have no idea what really makes bitcoin useful and what makes it command a high price in terms of goods and services or even fiat currencies like USD, are the ones who thought US real estate was a good investment in 2005.  These people do not understand what they're talking about.

I've seen at least two posts in this thread that explicitly show that the authors understand what currency is and have at least a marginal idea of why bitcoin is what it is today.
