a little dirty secret in Page Rank
There's a little dirty secret with Page Rank: when you place a link to the outside world from your site, your page rank goes down. Effectively page rank is a real currency and any link to external site is a leak from the web site owner's perspective.
So when spammers were using comment / link spam to boost their popularity they were really stealing. To combat this G* has proposed rel="nofollow" tag that a web site owner can add to any link and it will be ignored by the search indexer. Not only that violates the principle that web pages should be designed for people and not search engines, but it actually allows web site owners to game the system by trapping all page rank flow on the site and artificially boost the rating. As more and more sites are doing this, the web becomes less of a web and more of a star.
So the question you have to ask is what is the incentive for one site to properly link another? And what is the incentive for you to reference your friend?
