I'm always on here. I'm very wired in via iPhone, iPad, and laptop. I get email notifications to all devices on reviews, comments, messages, etc. Generally, unless I'm crazy busy at work (which is never during the holiday season), I'll reply in under an hour. Usually under thirty minutes. That basically means I'm on here all day. I check the forums when I'm bored and the new reviews. I do my own reviews when I get home from work and weekends. I also have bad insomnia so you'll see random posts and comments from me at 4am on stuff as well. So literally 24/7 for me.
As you might have noticed, I have no life. *shrug*
