The question is pretty much the poll.

I have been doing my programs in Object-Orientated Programming and I like it alot more, the code seems alot more neater and all.

What about "you's" ?

Everywhere it makes sense, I do it.
As you said, much cleaner, reusable, and even movable from 1 project to another.

Over the years, I've more or less made my own framework of useful classes I take along with me.

Nope. OOP isn't my cup of coffee. I have never done any OO programming or taken a class in OOP.
I studied extensively the C language but never gotten into C++ or C# which are Object-Oriented.

In most of my development I use OOP concept because it provides reusability. But when quick and customized development is required I dont waste my time in using OOPs.

Ohh, I see it was moved. I was merely referring to Object Orientated Programming in PHP rather than other languages thus posting it there.

PHP 5's OOP model is a great advancement on the previous version. I use it extensively.

OOP is basically a living, breathing set of functions. but it is barely procedural.

When there's a chance OOP could come into handy I use it.

In situations like shoutbox, polls, guestbook I may not use except I quite often use my own MySQL library.

sometimes, but i have a bit of trouble understanding some of the terms.

I seldom use OOP in my programs, unless really necessary.
mine's mostly structured.
