Google Indexes Faster Late At Night

I'm seeing 3 and 4 minute indexing with Google late at night. Must be less to keep up with after more people have gone to bed. I posted several articles on various blogs, all of which quickly indexed. Most of these blogs were aimed directly at my Orange County Photography website but, although the update on the sites all showed, nothing moved Orange County photography up in the SERPS for me, at least not right away.
