Yeah right, you had mentioned in your P.S. two other names dave and matt, I did a whois for those two and got some information:

https://whois.icann.org/en/lookup?name=matt.blog https://whois.icann.org/en/lookup?name=dave.blog

So yes it seems it got reserved. I wonder why too.

P.S. I'm a chris too ;) that's why im so interested in this, I own chris.lu but as it is a country tld this is not so good from a SEO point of view. I want to change if I find a better one, but haven't found one yet. Have fun with your new chris.lol :)
