My Technorati Authority Decreased

I'm back here! I just watched a movie for kids. That's what my dear HB told me. It is a kid's movie that I love. I told him that sometimes we have to be backed in childhood like watching fairytale and fantasy movies. But now, I really wonder why my technorati authority is getting low. I also noticed that some of my blogroll's URL changed to new domain name. Is it the reason why my technorati authority decrease? Or maybe some of my bloglink exchange delete my site to their list. I already caught some. I need to clean my blogroll in a couple of days. Once I don't see my site URL to those who exchange links with me, I am sorry to say but I will also delete you in my blogroll. It seems unfair if you delete my links. Peace!
