Great Barrier Reef underwater panoramas in Google Maps 
I might be missing something, but why is everyone so excited about this? If you want a great experience of the oceans and reefs out there, you could load up an HD video on YouTube of the Great Barrier Reef, and view something much more immersive.I'm a huge fan of street view, and I love being able to virtually drive to where I'm going, and find landmarks to help along the way, like for example, a large orange building next to the shop I'm planning to visit. How is ocean street view practical in anyway though? If it's for the user experiencing the ocean or planning their trip, they could upload a quick video of common snorkelling and diving points around coastlines and islands. It would give the user much more information. As of now, it's like flicking through a slideshow, and the navigation is brutal. I'm scratching my head here trying to come up with one thing this does well. As someone else said, I'd like to see more trails added to street view, or even more streets.Google, since you have free time, here are a couple of ideas...1. Street view for different seasons. In certain countries, towns and streets look completely different depending on the month. I frequently use street view to browse areas I'm looking to live, or travelling. It would be useful if I could switch the images to summer, winter, etc.2. Video street view. Much more time consuming to create, since the camera would need to stay in a single spot for a minute at a time, and blurring sensitive information would be more challenging. However, imagine choosing a location on the map, and feeling like you're in that area of the city, or on that quiet road in the middle of the forest where you rotate the camera and follow a bird flying by.
