New TLDs - Is There Any Real Benefit?

pigdawg writes "What is the purpose? What is the real benefit of new top level domains like .travel, .biz and .xxx? I don't believe these new TLDs will free up more names in .com or .org. Do they really think that orbitz.com will exchange their domain name to become orbitz.travel? Is the mostfrequenttypo.com porn site going to go legit and register under some new .xxx name? Again and again I keep coming to the same conclusion: given that many people/companies register their name in every TLD, it's all about generating more revenue for the registrars. What are your opinions on this subject?"
