I am hearing about .com's for about 15 years now. If .info gTLD can fail 99% of the new vanity gTLD's will stay dormant meaning DNS resolves but no visitors except you are someone like store.amazon search.google and buy.ebay, I've put .info in focus because, information is what we seek at a very basic level as human beings. Info is first. If you have to eat you have to have the information like Location, Quality and Basic Information about your Food; Otherwise you will not eat 99.99% of the time(unless Mom, Wife or someone shove in a milk bottle inside the mouth, dependency is what we dread as adults and wish to keep it in check, if this is how we think then gTLD is a risk that is not worth taking)
If we as people can collectively fail the .info extn we can and will mostly fail anything else that comes by. If .info was the first commercial gTLD available to public before .com, we would have miserably failed .com and will probably riding the .info bandwagon. We follow some universal behavioral patterns that cannot be overwritten(unless we can override them like in a sci-fi movie) and you ask anyone in this world who uses internet to check email about domain names, most of them will say .COM is the best. So what I am saying is not a Hypothesis but a Fact.
These fancy gTLD's are just Fancy in my opinion and will remain so in foreseeable future. So I will not be investing in it. If you ask me if I have ever dreamed about having a fancy gTLD myself? Yes I did and the gTLD in question was .domain as in nandas.domain LoL. I have limited this to dreams only.
Thanks,

PS: BTW if you are wondering why I said what I said, I used to have a .info portfolio that is 2nd to none. I have great love and respect for this extension. All we can do is work and work hard, fate is always decided by PEOPLE at LARGE. We are not in control, this vanity gTLD thing is luxury that I don't need.
