Like lots of products that get cheaper and less reliable, why can't they just leave well enough alone? Does Yahoo hire from the same labor pool that created that loser medical insurance website for Obama?
I would concede that there were probably lots of IT related problems, but I have been critical of a lot of the technical people too. The reason however that everyone had a problem was that they ignored test restults and just wanted to force everyone to try to use it. There are always problems when ever you try to do anything. Often you do see website churn, real improvements are rare.
