Do I know you?

I was looking at the map I have located on the sidebar of my blog and noticed I have had people from all over the globe read my blog.  I wonder if they stumbled on it by accident or if I have become someone's "imaginary friend".  I have some "imaginary friends" too, meaning I read their blogs from time to time and they don't know who I am.  If you read my blog from time to time and I don't know who you are, send me a note.  I would love to get to know you.  We could be pen pals!
