Please don't get me wrong, I am not defending the extension. As I mentioned above, I only have 1 name within this extension (just to hedge my bets really). If the extension becomes valuable, I have a great keyword name (with 151000000 global monthly search and $1.92 CPC) that took several months for the registration to come through.
If not... it was a $15 and a domain name that I can still have fun with.
It is worth the few dollars to me.
My original point however was geared towards XYZ and how they are/have been giving away free domain names. Second or third rung terms are going to be gobbled up (which they were) because... hell... its free.
When renewal time comes around... I do not expect those numbers to stay where they are (which is probably true of most new extensions).
Again not making excuses but even .Club saw a boost on 11-29-14 of 1965 names sold that day and 1735 names sold the day after considering the average has been about 550+/- names leading up to and since those 2 days. (.club has much better marketing)
It is not my domain extension of choice either.
I have yet to find a nTLD that really tickles my fancy but there are a few that interest me.
Cheers
