Paul notes the silver lining in this -- the more gTLDs applied for with "porn" identifiable strings ( that is what an 'extension's' nomenclature is ) the less likelihood of any governmental based "ghettoization" of porn might be.

With the new Trademark Clearinghouse there will need to be less in the way of defensive registrations. For larger businesses the costs are minimal -- if your name isn't worth the cost of trademarking then too bad I guess ... Without trademark ( registered or by judicial decree) you are precluded from the domain name dispute process anyway -- your decision, just be aware of it.

I think that ICANN collecting more fees in the light of a slowing of growth in the current gTLDs and ccTLDs is one aspect. Another aspect is the large body of speculative name registrations making many domain names unavailable in the more popular gTLDs.

The days of dot com being king may be on the downside now and that will affect a lot of investment. The value of the new gTLDS will depend a lot on the search engines reception of them. Today the search engine's preference for the TLD is overestimated anyway. The content and user acceptance is more weighted today.
