What are the first things that come to mind when you talk about .Net?
For me it reminds me of the early days. It also reminds me of techies. It reminds me it is not .com and is the consolation prize.
It also says something about longevity as it is old and established. So .net sounds foundational and institutional while .biz sounds like a fly by night. Just saying'.
So with .Whatever that further defines and accentuates more established extensions intended or not. It does not mean that .mobi will be revived. It does mean that .net could emerge with a clearer identity than it has had before. I see it competing with .web perhaps. Of course I am sure .web wants to compete with .com.
But what I believe will happen is all the current extensions will get a second look. Some will look better than others and so while everyone is looking in one direction, don't be surprised if something flashes from a direction that could be surprising.
What happens to business when 700 gTLD's come out and the one that adds the most registrations next to .com is .net and at an accelerated pace? What happens when you add up the increases for the current extensions and their growth is bigger and faster than the growth driving it?
All I am saying is expect the unexpected. And when you expect the unexpected you don't just throw yourself into something. You observe. Kinda like the stock market. You can get killed between 9:30 and 10AM. Best to let things settle in and then take a fresh look at what things look like.
