There's been a lot of clever and creative thinking posted about this issue....great discussion.
...But, I wonder if, in the end, this will be a storm in a teacup....Just a sideshow, in the big scheme of the internet?
For example, I don't know why .travel failed....Its a perfect term for a TLD .extension IF ever a category keyword .extension was going to work....But, it didn't work....Was it poor execution? Poor strategy? Insufficient funds to promote it?...
...Or, was it just an unnecessary, counter-intuitive, fragmentation too far...?...ie 'Nice-sounding idea - lousy practical concept'?
If I want to check out travel options, I wouldn't type in Hawaii.travel, Or, London.travel....I'd just type in 'Hawaii', or 'London'....Or, I might type in 'Hawaii.com, if I thought of it - or, 'Hawaii.mobi', if I was on a mobile phone, and see what options come up, and so on.....But, 'Hawaii.travel?...Well, history has shown us that people just don't type that in.
So, how would people react to an extension like, say, .beauty?...Would we type in cosmetics.beauty? perfume.beauty? facials.beauty?...
...But, what if (as will be likely) there are ALSO extensions like: .cosmetics? And, .perfume? And, .facials? etc etc
...ie a cascading fragmentation of '.extensions' within the 'Beauty' category - but, separately owned, and separately promoted?
...And, the same for every key category??
Very quickly all these keyword categories would become a mess - with totally splintered markets - and, like .travel - be virtually worthless, imo.
There may be a case for some major corporates to have their own brand extension - eg .microsoft, or .ibm, or, .toyota - because they could educate the market to expect to find everything you need to know about their own specific products/services...And, they are big enough - with a broad enough product range to justify it.
But, generic .extensions?...And all the sub generic .extension category fragmentation every one of them will attract??
I think people will just go on as they've always gone on - ie just type in the keyword(s) they want info about - and, leave it to the search engines to find stuff for them...and, the 'extension', per se, will add little, or no, value.
I don't see this 'Balkanisation' of internet extensions going anywhere - in the same way .travel failed to gain traction - and, probably for the same reasons.
Quite simply - the market doesn't need them.
