Personally... I am not excited about .XYZ and its prospects.
It is fairly widely known that a number of free domain names pad the registrations (it is thought to be in to the tune of 350k free domain names that where give out), based on comments Negari recently made to The Telegraph, in which he stated that .xyz, which had about 850,000 domains in its zone at the time, would have 500,000 registrations if the freebies were excluded.
It is also "alleged" that NetSol was paid $3 million to to bloat up the .XYZ numbers which corresponds with Verisign's lawsuit against .XYZ for allegedly “false” advertising.
I can not seem to rally behind the idea of .XYZ.
The numbers mean nothing, as they have been padded through multiple means.
Negari has stated to have gotten rid of all his .COMs but he still owns several valuable ones.
There was the rumor that Negari started about Google wanting to purchase .XYZ and he would not sell it.
It seems to me that this entire extension is all smoke and mirrors. Illusions used to make the extension "seem" bigger then it is and when that fails... more shenanigans to put it back to the limelight.
And like Enron knows first hand... once that corporate veil is pierced, it will be those who are standing around holding the bag (domain names in this case) who will be the losers.
Just my personal opinion based on what I see.
Cheers
