I have two questions here in fact..
1) What'a an effect of outbound (external) links from a webpage to its PR, if there was any effect?
2) What's the PR "real" range, not that 0-10 range?
Everyone know that one link from a PR7 webpage can raise any other page to PR6 (if the first has a suitable number of outbound links, of course!), while applying the PR formula on that latter webpage, it wont get more than something like 0.1 PR!
I hope I made my questions clear.
Cheers,

Answering this questions always results in lengthy discussions:
Do outward links increase pagerank? [webmasterworld.com]
The Value of Outbound links now... [webmasterworld.com]
The (dis)advantage of exchanging links [webmasterworld.com]
External Linking help or hurt? [webmasterworld.com]

The ToolbarPR is an interger value which is related to the real PR on a log scale, e.g.
real PR <-> ToolbarPR
<1 : 0
1-10 : 1
10-100 : 2
...
There are different opinions about the value of the logarithic base (which is 10 in the example above) ranging from 5-23. I like the higher value.
Now my question is, what would be the logarithic base? A top secret Google information?
Yep. And, this isn't all that important of a detail. As an SEO, I'd say worrying about what is the weight given to PR in the algo is more important than the log base.
