Why link?

I have been pondering what the value of linking to other pages is and have decided to investigate the topic further. The post right here explains it far better than anything else I have read to date. What I arrived at from this information is that linking can be an effective tool in the SEO game but only when used judiciously. There are different ways to link to the same site that will produce different effects on your SEO and choosing wisely is key. While I love just about all things "free" do your homework before aimlessly linking to everyone who asks.
