Hi guys, if I build a strong domain with many backlinks, and thus increase it's PR, will this also boost my other pages? Such as www.mymoneysite.com/money.aspx?

Because I constantly see pages from web 2.0 that have a really strong domain with pr 7+, but when you create your own page on them its pr 0, does this mean it's useless?
 
The pagerank from the homepage will trickle down to your inner pages.

First of all, why would you think that a link from a page with PR0 is useless? The PR of the page is just one of many factors.

Second, many of these web 2.0s do a good job of passing link juice around. Yes, when you create the page it will say PR0 but that is not necessarily its true PR. Any new page anywhere willl say PR0 until the next Google PR update but Google sees PR as dynamic, always changing. We see it as static because that is how the Google toolbar shows it. So it is possible that sometimes you will create a web 2.0 and within an hour Google sees it as a PR2 even though you still see PR0 on the toolbar until the next update.
 
I see, makes sense.

I don't think it trickles down a lot thou, because otherwise all search results would be youtube videos and what now.

Maybe its just a small percentage.
 
This is just a guess, so feel free to correct me if I am wrong.

But I would assume that a homepage with a high PR would trickle some of that rank to other pages, however as you get more pages (with 0 pr themselves) the effect of the home page PR starts to diminish.

On the other hand if some of the inner pages begin to develop their own PR (through various link building methods) then it lessens the amount of juice it needs to suck from the home page.

I kind of look at it as some sort of Charger or battery. The Charger has a certain amount of "juice" it can push out, the more devices I have pulling juice from that charger the smaller the amount of juice it can give you, now if I attach another source of juice to one of the devices it likely will get more charge from the 2 sources of juice AND put less strain on the original source of juice.

So while I have not dug too much or looked this up just based on what I have read here that is my basic assessment of PR and how it flows out.
 
Also, is it just me or do NoFollow links help you rank? I was looking at the backlinks for one of the sites in the top 10 for "buy viagra" which is a very competitive keyword, and most of the backlinks where noFollow.
 
Depending on the number of links on the page, a child page gets a certain percentage of the link juice from the PR7 homepage. The more outgoing links, the more the link juice is spread among the links. So, a few outgoing links is still a good situation; 100's of links or several pages removed from the PR7 page dilutes the link juice and makes it almost worthless.
