I think that there was no end-user demand whatsoever for more so-called DNS extensions, [or] global generic top-level domains (gTLDs)," he said.
I run a lot of websites and it was a pain to find good domain names in the last 15 years. With all the new TLDs that problem is completely gone.There will be a time when the multitude of TLDs won't bother anyone. Limiting TLDs doesn't add security. Educating people about the dangers of the internet does.
