Viewer counter

Yesterday I set up a viewer counter. As the name indicates, it supposedly counts the number of viewers of this page (see the bottom of the side bar). It shows 245 people (as of 8:00 a.m.) have visited here within just one day. It's an amazing number, considering only 6 days have passed since I opened this blog.
Here are two questions. How did they manage to get here? Why didn't they leave any footprint at all (except for 3 active people)? A possibility is they came here using keywords and they found no interest in my diary and just gone. I know how frustrating and sometimes even painful it is to express anything you want to express in English. But it takes that much effort to change it from agony to that much fun. That's life!
This picture is my favorite, taken in Lugano, Italy. The two men are a captain and a crew of a ferry boat waiting for voyage. Can you tell which man is the captain?
