People think Bitcoin is funny money and Google Glass has no specs appeal -- if they even know what these new technologies are. Many people are still unaware of Google's smartglasses or digital currencies, according to new research from the UK, and those that do are worried about the privacy or financial issues of these hot new areas of technology. On the day Google Glass went on sale to the public -- for one day only -- Gorkana surveyed 1,000 adults in Great Britain and discovered that 68 percent of those polled flat out don't know what Glass is. Part of the problem is that Glass is only available in the US. But of those who have heard of it, almost half are concerned about the privacy implications of Google's smartglasses, with one in five thinking they should be banned from public places.
