That is not a reliable way of measuring web usage for any TLD. This is because active websites in new gTLDs often forward to primary websites in other TLDs. Some of the stuff I've read about usage in new gTLDs is completely laughable in terms of "methodology" and sheer cargo-cultness of measuring what is and is not an active website. Not every new gTLD is a wasteland or zombie TLD. Some are doing quite well in terms of renewals (a few have higher first year renewal rates than .COM) and usage.Furthermore, you can check the usage of any new TLD by searching Google using "site:.tld".
Domaining in a new TLD is a double edged sword for the registry. It needs to kickstart awareness for a new TLD and domainers do this for free. However, domainers keep potentially development worthy domain names out of general circulation and it is more important for a new TLD to show evidence of development as that drives awareness moreso than domainers. When users see more developed websites in a new TLD, they become aware of the new TLD and may develop sites on it. Only then will any sort of reliable secondary markets develop. Other than that, domain name sales in a new TLD are on a par with burger flipping.The problem with these new extensions is that not only is the amount registered meagre but the *very* few sales that have occurred have been enough to rope people into paying the registries ridiculous amounts of money for, basically, lottery tickets. I could see value in them developed and producing and it may even help them to be accepted mainstream. Unfortunately they are bought in the hopes of reselling as-is.
i think .bid has some interesting possibilities
