Yesterday I came across to two glaring examples of misinformation. One was on the News vine site where someone had posted a story about presidential hopeful Obama. Without wanting to focus on the story as it has been removed It was quite clearly unfounded. But it does show how important it is that we remember the old motto believe nothing of what you hear and only half of what you see. Of course a web 2.0 social community will provide some form of control and editorship in place of where you may have a lone blog spouting misinformation.
That is the problem in general with speculation, rumour and the internet. There is an awfully lot of information out there that probably is not correct but we have no idea how much. The number of dodgy e-commerce businesses that I have seen is really amazing. All sold by promises that they can never hope to achieve. If something sounds too good to be true it probably is on the internet. If there is none of the usual tracking methods such as feedback, users comments, transaction history then be very suspicious.
