I personally don't favor the industry TLDs except for .xxx (as it provides a convenient way to screen content for various audiences). I know that the foundation of DNS is industry-specific namespaces (.org .com .net .mil) but it doesn't seem relevant anymore.
It is going to be interesting to watch how the whole TLD "opening" is going to develop. So far the addition of new TLDs made more or less just the value of .coms stronger. Hard to predict how this is going to change when every ad on TV is going to have a different TLD.
