Google Page Rank Infomation - Is this correct?

I am hoping that some of you will comment on this post. I found an article on Google Page Rank on the web. It may be dated, since it was written in August of last year, but I wanted to ask some questions based on it. The article starts here:
http://www.search-this.com/google/go..._explained.asp

and goes for several pages. I am going to snip some info from it in this post.
<snip>"share" = the linking page's PageRank divided by the number of outbound links on the page.</snip> and <snip>A page "votes" an amount of PageRank onto each page that it links to. The amount of PageRank that it has to vote with is a little less than its own PageRank value (its own value * 0.85). </snip>
<snip>The result is that it reverses the previous conclusion, so that a link from a PR8 page that has lots of outbound links is worth more than a link from a PR4 page that has only a few outbound links.</snip>

So, my incoming link preferences (what I am striving to accomplish) would be in this order:
1. High ranking pages or websites that link to my page on a page where no other links are placed.
2. High ranking pages, that have a PR above 7 or 8 that link to my page from a page that has few outbound links.

<snip>The maximum PageRank in a site equals the number of pages in the site * 1. The maximum is increased by inbound links from other sites and decreased by outbound links to other sites. We are talking about the overall PageRank in the site and not the PageRank of any individual page.</snip>

This one showed me what you guys have been describing as 'leaking'. I have a lot of outbound links, which means it is really important for me to get those 'correct' inbound links. But, according to this article, it is important for me to avoid<snip>inbound links from link farms can damage the PageRank and the site, and should be avoided.</snip>

I found this a little conflicting with what is happening on my site. <snip>The page that you link out from makes a difference to which pages suffer the most loss. Without a program to perform the calculations on specific link structures, it is difficult to decide on the right page to link out from, but the generalization is to link from the one with the lowest PageRank.</snip> I have a page with hundreds of links outgoing and it has a PR of 4. The only link going to that page is from my own pages. Maybe the thing that helps is that I have a link on each of my pages to that particular page, and my overall site has a PR of 5.

<snip>To a spider, www.domain.com/, domain.com/, www.domain.com/index.html and domain.com/index.html are different urls and, therefore, different pages.</snip> Based on this assumption (read the rest of this), then any division of the domain would cause the page rank to be separated also. Therefore, as I have asked on this NG before, www.domain.org and subdomain.domain.org would need to establish their page ranks separately. Whereas, www.domain.org and www.domain.org/subdomain/ would garner some 'advantage' from each other. So, if I am adding new elements to a website, and I want to take advantage of the current PR, then I need to add them as a suffix. On the other hand, if I add them as a prefix, and I can include content that is considered relevant to searches, I may have a chance of getting a good ranking on that site and links back and forth might help. I am going to try it the suffix way first, then move to the prefix, if I believe I need to do that.

So by breaking a site up over multiple domains or sub domains you may
gain more organic links. All depends on the sites really.

Thnaks for answering Dave. One quick question, if I make a whole bunch of
separate directories by cancer type, which will be better. Example:

www.rare-cancer.org/pediatric/retinoblastoma/
http://www.rare-cancer.org/pediatric...etinoblastoma/
pediatric.rare-cancer.org/retinoblastoma/
pediatric-cancer.rare-cancer.org/retinoblastoma/

Keep in mind that retinoblastoma is searched for far more often than the
term pediatric cancer, according to wordtracker anyway (I am still not sure
this is a good guage on what people are searching for on Google).

That's not correct.

PageRank is page based not site based, so when thinking about PR it
doesn't matter where a page is located all that matters is what links
to it.

If you have a page with one link to it Google should find it and it
will receive a share of the PR from the linking page. It doesn't
matter if the linking page is on another domain or the same domain.

To give you an extreme advantage PR wise there is no difference
between 1000 pages hosted on one domain and all linked together and
1000 pages hosted on 1000 different domains (or sub domains) and
linked together. The PR will be the same.

That said there are benefits to multiple sites in obtaining links. If
you have 10 sites about the same subject, but with slightly different
themes. In your case Adult Cancers, Paediatric Cancer, Rare Cancers,
Site About a Specific Cancer etc... each one is more likely to gain
links from a specific type of web master than having one large site.

So by breaking a site up over multiple domains or sub domains you may
gain more organic links. All depends on the sites really.

Hi.

Better depends on what you are trying to achieve.

If it's just the one keyword retinoblastoma then

'retinoblastoma.com'

is the best domain. If you are after the one word and 'keyword
regionalistic and the keyword is cancer then these might be better-

'retinoblastoma-cancer.com'
'cancer-retinoblastoma.com'

If you don't want to make new domains there are sub domains-

'retinoblastoma.rare-cancer.org'

Or there is the easy option, sub folders-

'rare-cancer.org/retinoblastoma/'

Or file name-

'rare-cancer.org/retinoblastoma.html'

And of course a combination of the above-

'retinoblastoma.rare-cancer.org/retinoblastoma/retinoblastoma.html'
think this is way over the top.

Which one you choose (if any) is determined by looking at how
difficult a keyword is and in the case of domain names if it's
available. Also how much content you have.

If you have a lot of content I'd go with the sub domain-

'retinoblastoma.rare-cancer.org'

As I explained by email previously this or more likely to get listed
in it's own right at places like DMOZ.

If you plan to break your site up into sections then I'd look at this
sub domain-

'pediatric.rare-cancer.org'

And have the folder-

'pediatric.rare-cancer.org/retinoblastoma/'

This gives you all the main keywords once in the domain/folder name.
You could then add further keywords to file names. i.e.

'pediatric.rare-cancer.org/retinoblastoma/support.html'
