Microsoft Corp is visiting my Blogsite?

I found a series of 60 IP addresses last March 13 and today on my blogsite coming from Microsoft Corp thru search.live.com. I wondered why they were visiting my blog. Still, I considered them my awesome visitors. So flattering but a little bit confusing because they were looking and reading some of my blogs. I don't know what they were after with. hehehe. It could be my wrong grammar, my own domain GiggleYohoo, the copyrighted content which I copied from other sites or maybe they are tracking me. Hehehe. Anyway, if it is all about the copyrighted stuffs please message me and I will remove it immediately. Nevertheless, thanks for visiting my blogsite. You are soaring up my traffic rank. Thank you.
