Maybe those were the ones he missed when unchecking autorenew? My gut is telling me that we did not intentionally renew these names. I think the common wisdom now is that .CO is toast. IMHO.
My hunch tells me you also would have claimed that "hyphenated .DE names" aren't worth reg fee and should be dropped immediately - in which case I would be out a 1000 € sale this week.
There are those who share your opinion, which you're completely entitled to hold, but you're clearly biased, and I don't think anyone considers you an arbiter of what the rest of the domain investment community is doing.
You've made yourself abundantly clear: you feel .CO is worthless.
It's important to hear both sides of every story, and I appreciate that you've felt the need to repeat yours dozens, if not hundreds, of times.
It doesn't matter how many times you ad "IMO" to a post - we know that's your opinion. I don't know why concentrate all of your time in a thread in which you have no vested interest, though. Let the rest of us drop, research, invest in, and sell the names that WE see value in. Unless you are fluent in every language and have published sales in every ccTLD, you
can't possibly speak for the entire domaining community. Do you think statisticians would say 2 years (yes, I know .CO is technically older than that, I'm talking about this time around) is a long enough time to establish a trend? You usually require a much bigger data set.
Aged .coms are the most liquid investment, but there are sales that defy expectations and "common wisdom" every day.
