vote for Tajmahal- Is it authentic?

These days, I am getting many forwarded mails, saying "Vote for taj" thru this site(http://www.new7wonders.com , http://votefortaj.com/ etc) or SMS to this number to include our TajMahal in new seven wonders. Some how, I didn't wish to do. I don't know the exact reason but I am not interested to do. May be, I was thinking that it is not authentic. May be, the way they are saying (Here is the chance you can do something for your dear nation) didn't give any impression that it is authentic. One feeling I had is, there are many other issues on which we can fight (poverty, casteism). But, I had a small doubt some where, whether I am lazy to do so that I am giving all these reasons for not voting. But, seems, I am not. Here is one link that I got which says that it is all marketing strategy that these people came up with.
