Technorati Authority

For what it's worth, can someone please tell me why this blog's Technorati Authority still displays 44 when it should already be 70? Well it's been maybe a year already that it got stuck on 44. I have installed and re-installed the code several times already to no avail. Anyway, it's not that I am really concerned about my blog's statistics, in fact the only statistics I'm concerned about is PR, who doesn't? LOL. But just so my blog displays the correct stat, I would like to know how I can correct that. I actually reported this to Technorati support but nobody seems to care. So should I even care? LOL. Anyway, I'd appreciate your help and your thoughts on this, thanks.
