Hi Mark,
All the myths about this over-hyped (out in the interwebs among the conspiracy-theory websites) but generally under-performing comet are exploded here:

The truth is that this is a small (about 3km dia) intrinsically faint comet that just might barely make it to naked eye visibility around Sep-Oct. It will be a nice-ish comet for binoculars. The closest it passes to Earth will be about 35 million km (ie nearly a hundred times further than The Moon). That fact has been well established and known for nearly a year. This body presents no danger whatsoever to anyone living on Earth. Just a couple of days ago a similar-sized comet (45P/Honda–Mrkos–Pajdušáková) passed much closer to the Earth (about 9 million km) than Elenin will, and ... nothing happened (as usual).
As jjj said, the reason why there hasn't been much in the media is because there is very, very little to report that the public would be interested in. There is no conspiracy on this. It is just one of 1000's of comets out there in our solar-system and there is nothing amazing or outstanding about it apart from the fact that it is going to pass closer to Earth than average. I have to stress however that every year, on average, at least one comet and many more (dozens of) asteroids of a similar size to Elenin will pass closer to the Earth than Elenin. You can safely ignore virtually everything you see on youtube about this comet.
Best,
Les D
