I was wondering if I should learn Object Oriented Programming.

I keep hearing people explain what it is, but I still don't get it. And I probably won't get your explanation, just a heads up.

Do PHP coders actually use this? I heard it was pretty hard.... also I was wondering if big sites use this also. All I remember is seeing a blog entry by an experienced coder and he was basically saying that it is harder than it looks.

I just don't understand the practicality of it all. Wondering if sites like digg.com or another really big site (like Yahoo answers) uses it. And, of course I mean with PHP.
