Does NASA's finding that life can use Arsenic as a building block for DNA mean anything?

So instead of announcing that they'd found life on Mars, NASA announced today that they have found microbes whose DNA can be made with Arsenic as opposed to Phosphorus (which all other living things on earth use). Does this really mean anything?
