I do plan on raiding again come Cataclysm, and that means I'll probably start up the blog again with frequent posts.
I've only done the Lower Spire in ICC10, and I plan on going further be it with pugs, or guildies.
You're not seeing a lot of activity on my warlock mostly because I've been levelling a paladin.
I think that answers the general questions in the few e-mails I've gotten. It's nice to know that there are still have some people interested in this blog!
