Unless a CC domain is already well known (such as the vg.no example above) it likely is not going to get much traffic. I get 5 - 10 uniques a month on my LL CC domains and that is probably above the average. And look at the value - sex.io is at $5,000 and it gets its own thread. Sex dot com is valued at several thousand times that, so I have heard.
.DE, .FR, .CN, .IN - the larger countries have dynamic markets in their own extensions. The small extensions are lost at the present time. A few are receiving publicity such as .TV and .CC - both are tiny islands but Verisign has the contract, so we hear about them.
