Google indexes my website immediately

I just noticed yesterday that Google indexes contents of my website immediately.
I used to have to wait a week for new content to be propagated across the net. Now, things appear as soon as I post them.
This is great news to me because I feel like I am being put on the same level as other major websites or news sources.
However, I am not sure if this is a privilege afforded to all websites, or only websites that have been specially earmarked by Google.
Anyways, don’t ruin it for me. Let me enjoy my naive glory.
