blogging privacy.. who's reading your blog?

I've been reading a co-worker's blog secretly - not in the stalker way, but she is a fabulous writer.. and rightfully so, as she is in communications. However, it was under the strangest circumstances that I stumbled across her blog. I had recently attended a cartoon art museum event and wanted to check out the artist's site, which happened to be in blogspot.. Using my personal work laptop, I typed in the address correctly, and it lead me to my coworker's blogspot page. "Strange", I thought.. she looks like ___. For a moment, I thought, "Wow.. she's secretly a cartoonist with an alias??" Well, that wasn't the case.. She was definitely not the cartoonist. It was a completely different URL.. I really have no clue as to how it directed me to a different page.. and then it magically went back to working correctly. Ever since then, I've been reading her blog. I'm reluctant to tell her because it is a very personal.. Maybe, I was meant to find it.
