Google Analytics

I was looking at my Analytics data and I was very surprised I have to say. The weird thing I found was the world map and how many people in different countries look at my site. Far away places like Brazil, Jordan, India, South Africa and the US(which is second place to Ireland in views). There are a load more other than that.
The browsers and operating systems that visit my blog is also very interesting. Firefox is top and in the OS visits its Linux (50 views), windows(28), Mac(6), (not set)? (1) and 1 visit from an iphone. I dont know what not set is lol. Linux is obviously top because thats what I blog about most and windows and mac views aren’t surprising but I wasnt expecting any views from mobile devices like iPhones.
Id love if analytics could pick up if they came to my blog by mistake or they are actually interested
