Except for those that are supporting the $250M, it seems. I remember when lots of original backers left, many here even got refunded. But, you cannot tell that by the overall money they have collected. Thus, the money does not support the many people do comment. Unless you have specific # of backers in 2012 and the # now and it has declined. In which case, we could infer that the general population cares, but, some whales don't.
