The .Design extension launched into general availability on Tuesday and ended with 5,204 domain registrations (according to nTLDstats.com)
The 5,204 count includes all registrations during the Sunrise period which could only be completed by Trademark Holders and those who paid an extra fee to get early access ahead of the Early Access Program.
Looking at some of the domains, it appears many of the good ones have already been snatched up. Have you registered any? Planning to register any in the future?
