Why invest in a TLD that has virtually no local market ?
This applies to many extensions, not just .ws.
I'm assuming that you are referencing the PensacolaBeach.ws domain? If so:
1. Pensacola Beach is where we vacation and the whole family enjoys the experience. I'm currently in the process of teaching my wife and kids HTML, WordPress, SEO and Photoshop so it's more of a learning project. If it makes a few bucks in the process, whoop-de-do. The best available .com was PColaBch.com, which I did register as well.
2. .ws is marketed as "web site" which I realize is just that, marketing, but I'm willing to market in the same manner. It's a stretch, but worth it I believe if a short, generic keyword is available to hand reg when logic would dictate that the .com will never become available. In other words, I believe that PensacolaBeach.ws trumps PensacolaBeachVacationFun.com
If I misunderstood your question, please excuse me and clarify.
