This is a two-for-one free lesson. It's worth way more than ten bucks. It's probably worth more than the last 12 Frank Kern videos you watched combined. (Of course, if you already know what I'm about to tell you, it's worth nothing.)
The first part of the lesson: Page Rank only matters when it's another site linking to yours, and then it matters a lot. One PR5 link (not watered down by 5000 other links on the referring page, of course) from a related site will cover all your backlinking needs, even for competitive terms.
The second part of the lesson, the part that you can put to use right now: When it comes to backlinking, EZA is not the be-all-and-end-all. Links from articles there generally don't even show up when you do a "link:www.mysite.com."
Here's the takeaway: Buzzle articles are PR2 right out of the gate. (If you already knew that, sorry for the hype.) The links are also not as watered down by jillions of other links on the page.
EZA articles are PR0 or PR N/A. Sometimes you can get them up to PR1 if you backlink like crazy but why bother wasting your time backlinking to EZA? You're already doing them a huge favor by giving them content.
This is not to say that you shouldn't submit to EZA -- you should. Traffic from there is great. There is more potent link juice hanging low on the vine, though.This is not to say that you shouldn't submit to EZA -- you should. Traffic from there is great.

PS -- Third "bonus" part of this free advice: Good SEO tools will put the big juicy steaks right in front of your face. That's all I'm saying about that. I'm not about to give away the store, here!
