Chances to increase page rank?

Told you I’ve been surfing and maybe got addicted to this blogging thing, so I’m searching for ways to increase the page rank of my site. Read somewhere that saying in order to have a higher rank, I’ll need to have better traffic both in and out from my site. As for the “out” part, I can easily do that by linking others from my blog, but as for the “in” part, I’ll need to registered with search engines, or get people to link back to me which is quite limited on my resources.
Then stumble upon this site that is offering the service: Buzzfuse.com. It allows you to sign up for free!
This site will then be able to increase the traffic on my blog and hopefully raise my google ranking.
So, why not? Try it, I did!
