Ok.., but what does any of this matter to the success of an extension, new or old? .Tel may live in the twilight zone, but the extension is still out there, and used by those that want to use it. .Mobi is considered a 'failure' extension by domainers, yet is used heavily in Africa and other countries. And how or why one runs a registry, or whether or not they meet their 'expectations', again, has nothing to do with an extensions viability. If they F-up the biz and belly up, someone else takes it over and it's still out there being bought and used. (ala .mobi) So is it the extension that failed, or the people that ran it failed?? What I usually see, is that it's the extension that is not the one 'gone'!
This whole "..whatever....proof of doom" scenerio braggadociosing, is that some feel if an extension doesn't have big reg numbers, ala .com/.net/.org etc., or is not popular enough to be re-sellable, then they are failures and people that buy/use them are chasing fools gold (or whatever derogatory term that's thrown at them), and are/will be failures. Yet, I'm hard pressed to think of an extension that 'failed and was decommissioned' and taken away to no longer be used.
Perplexing...
