User blog:RustNSplinters/New to the Site

Alright, someone do me a lemon and explain things to me:

Can blogs be seen by everyone, or only when people go to my page?

What is the "talk page" feature, and how is it different from "Blog"?

Where should I put Creepypastas? Talk page or Blog? Or somewhere else?

Am I fully able to modify other pages, or does the modification have to go through the person that posted it?

I'm sure I'll have more questions later though...
