What does this mean?

Is this common or what? I know I posted about this earlier, but I really need to know why this is happening..

Like, every time I make a post - within 1 minute my post is showing up on Google's search engine. For example I just wrote a article about how to increase site traffic through social networking, and like one minute after I published the post it was already on page 3 of searching "increasing site traffic"

Is this common or is this me being very lucky? Does this mean google is constantly crawling my site?

The big G sees you did it- Use a different computer and or IP- have a friend do it for you. bet you don't get the the same results. just a test.

I know that you can control how many times google will crawl your website through the google webmaster, but maybe it's because you keep pinging your blog?
