Does posting viral/funny content get you more friends on facebook?

Facebook is the only social media nut that I'm having problems cracking.
To me, I see 2 ways to utilize facebook (aside from PPC)

You can post casual, yet informative content on your niche.
Or you can post crazy/funny content that everyone will like.

But posting funny content about my niche... doesn't seem possible. I can't think of 1 funny thing to write/post about home improvement. So instead, I just try to post helpful information.

Well I've gotten a couple leads off facebook, but for the most part I still feel like I have no idea what I'm doing.

Is the better plan, to just post outrageous content that people will share? Even if it has nothing to do with your niche?

I'm not understanding the more intricate social dynamics of facebook. If I post something thats both original and funny, and people share it, will that actually trigger people to add me as a friend?

Right now I have like 200 friends, most from highschool and college. Then there are tons of people I can add, that I know, but I don't like adding friends. It takes forever. Plus I feel like there's got to be a better way.

I sound ignorant to facebook because I am. I set up a profile there 3 years ago, but barely used it. Mostly because I didn't like facebook. Untill I got into marketing and realized I need to learn how to use it effectively.

So should I just forget about posting useful content for now? Would it be better to just focus on entertaining people & getting attention? Then if I get a lot of people befriending me, I'm thinking I can save promotion for later.

Good idea or no?
