It will take time for such GTLDs to get popular but if its available at cheaper price then its good to register your choice domains before anyone else registers it.
I send this around in my newsletter, I think it makes my point very clear, in the beginning I was not sure but now few years later, I can say it sucks.
Is it a hype or a horror? Or maybe something in between? June 13, ICANN announced the list of applicants for 1,930 potentially new top level domains, including many doubles. Broadly speaking there’re two types of new TLD, the .brands incl. Cities and the poor rest. The brands might have a chance because of their visibility and maybe endless money. Sorry guys, talking about the rest … to many of them I meet during Icann Prague, I am sure that most will fail or rest somewhere in the corner. So many without strategy, just hoping that registrars will implement them is not enough. They rely very often on an imaginary community, but there are approximately 280 TLDs existing today without internationalized TLDs, it seems to me that some of them are hoping for luck or being bought by their competitor.
For all the money spend and people behind I hope that I might be mistaken.
New businesses will even more carefully evaluate in future, behind which domain/TLD they set their internet presence, niche TLD´s which might confuse the consumer/users or choose an established ccTLD or gTLD. Picking the right domain name was always a fundamental decision for the business, and domainers said this always. From now on I believe it will be even more important to pick the right domain under the right TLD.
