As far as I can tell it might be a little while before some of the TLD are supported by major browsers without an extension but I do believe support is inevitable.
Domains are a great blockchain product in my opinion.
Another aspect is products that can be tokenized without a company controlling things. The smart contracts are really cool in that you can make it so that you get paid a percentage of future sales. Forget about digital photos but think of it from owning a musicians album (royal does this).
These are things that can be done without the blockchain but you end up paying companies to manage it for you. They also set rules and they can also cancel you. Free from management fees and no company dictatorship.
