PR is an exponential power (a small number used to represent a much larger number) derived from nothing more than links.
Actual rankings depend on millions of variables, several of which involve links.

Steady on Diego! Ease off the knee-jerk reactions.
I understand perfectly well what Pagerank is.
Taking your statements, I produce a
reductio ad absurdum as follows:
Premise 1: Pagerank does not affect search rankings
Premise 2: Pagerank is a measure of how important your website is
Conclusion: Your search rankings are not affected by how important your website is.
...which is patently false, so I have the desired
reductio. Therefore one of the premises is false; I blame premise number 1.
I never said that search rankings are
the same as Pagerank. Obviously they are completely different. But for any given search subject, the higher-ranking pages will tend to have higher PR.
In case you deem this to be true parellelism -- mere correlation with no causal element -- let's look at what Google themselves say:

One more thought on this subject: if Pagerank does not affect search rankings, then what
does it do? So as well as my
reductio, I can hit you with a "spare wheel" argument.
And technically, Pagerank representation (0 - 10) does not follow an exponential scale. It follows a logarithmic scale. Log(x) is the inverse of e^(x). If Pagerank were exponential in "link popularity", then it would become easier and easier to go up a level, not harder and harder.
It's also difficult to judge what base the logarithmic scale uses; it isn't necessarily base 10.
Finally, we don't know whether Google uses "millions" of factors to determine rankings. No doubt they use some large number, but not necessarily "millions".
