OK, I've seen this posted around the different forums that .club is going to make it really, really big but I personally believe that 1 million registrations by the end of the first years is a big stretch. What's crazy is that they could have said 200,000 and everyone would have thought that was a lot of domains. If they pass the 200,000 mark they will look like heroes but now they've set a bar so high that it's going to be tough to reach.
Don't get me wrong....I wish them all the best. I wear their polo shirt all the time....it's really comfortable. :-) The problem that I see with many of these new extensions is that many of them have had to get investors to "drink the kool-aid" and this has set them up to fail. I personally think that about 98% of them will go down and be snapped up by some of the more successful ones....by hey, it's a gamble and people with a lot of money seem to like doing it.
As for me, I'm going to stick with .com and some of the ccTLDs as I know for sure that they're not going to vanish in a hurry.
