I totally agree with Whois-Search on this one. The value of the domain is in it's developed state. If it's a "keyword" that makes it even better. For many reasons, not forgetting people have to "remember" your URL to ensure they come back. I have given my .ws addresses to family and friends over the phone, and didn't have to repeat myself. I did have to explain where the ".ws" came from. Nothing indepth, because what they keyed in on was the "Keyword" part. As far as the ".ws" part I explained to them how the dot com version of the name was taken back in the early 1990's so "other" TLDs (including ccTLDs) are being used like never before. People can relate to that.
my ratio of sites now are:
1 biz
7 .ws (4 in development)
1 info
edit: Make that 8 .ws names. Espanol.ws just dropped...
