Which WoTLK realm is the freshest?

[Kruxx]

Hey,

Was curious.
Which of the WoTLK realms is the freshest one, and how long is it since it was released/reset?
Been getting the itch lately but don't feel like going in on a realm that has been progressing for ages.

Sorry if this info is available somewhere, I tried to find it but didn't succeed.

Regards

Lordaeron is the freshest realm, although it's not fresh by any means.
