Wow!
So much information to take in here. Thank you Greenie, Linkster, and Halfdeck for the replies.
Linkster - There was some confusion on my part, no doubt. But, when I say PR, i am referring to pagerank not really what the little bar shows. I did a LOT of reading yesterday and last night on this topic on various boards and I read about much of the same things you are saying now.
I was aware of how others could redirect their PR and make a site look higher than it really is, but for the most part I'm trading with people that post here on the board and don't think it'll happen to me.
I'm not trying to base my business model off the green toolbar, just trying to learn and improve, that's all.
Those last 2 posts were great, thank you for information.
Greenie - Thanks, yeah I just like the way a high pr toolbar looks.

But I do value Linkster's, and even DD's advice, ths the reason I posted the question here.
Halfdeck - "A better indicator of domain strength is freshness of cache dates and the number of pages in the main index (as opposed to pages labeled as supplemental)."
Wouldn't that be determined by pagerank or no?
Thanks for replies also, very informative as usual.
Sorry this is the "10th PR Thread This Week" but it is loaded with a lot of very good info and I would of hated to miss out on this. I'm guessing many others will get a lot of good value out of this thread.
I have a better understanding now, and I thank you all.
