This may seem like a dumb question, and I think I intuitively know the answer, but there is no such thing as stupid question, right?
Concerning the stats on my dashboard. I only have two posts, so I just started. I see that those posts have 3 visits each. However, when I look at the graph above, it seems to indicated that I have had 40 visits. Is the difference simply between how many have visited my post and how many have visited my blog without clicking into a post?
