Kev and I both were hitting on top words in obscure extensions, like poker.ext, business.ext etc. I had also done some .in, .cc, .tv, and some other more mainstream ones and my largest sale ever is a .in, but again there was a time when the obscure extensions were gold mines as long as you went after the right words...like poker in any extension was min $1,500 reseller vaule for a while and that wasn't that long after there were probably handfuls sitting around to register. Now anyone getting one is getting it off the drop and having to move quickly even to do that.
I'm not saying there's NO opportunity in ccTLDs, but I don't think it can exactly be considered a hidden gold mine anymore. Maybe the only area I can think of that doesn't get hit quite as much still is ccTLD typos of sites, but you reeeeally have to know what you're doing still to get the good ones because you don't have the luxury of a grace period and the reg fees are a lot higher. In general though ccTLDs are now more or less on the same playing field as the other niches in domaining and just like those, one must factor opportunity vs. competition. In 2004 there was verrry little competition in the obscure ccTLDs - like shooting fish in a barrel for those of us paying attention to them, which was the point I was making - getting in on ccTLDs in 2004 is equivalent to getting into the major exts at the turn of the decade or earlier. This program even in 2005 or 2006 would be great timing - now I'm not so sure it's that easy to get into.
For what it's worth, anyone wanting to get into ccTLDs I would suggest do some heavy research and/or get knowledge/expertise through someone with a lot of experience in them like you or I because it's a whole different mindset than .com domaining, that's for sure.
