Less than 1 month since this site was started its been very noticeable that googlebot likes the site and url structure.
At the time of writing it was noticed that the front page has been given a google rating of Page Rank 7.
Topics and articles and pretty much everything directly below the frontpage are PR6.
I noticed with topics when they were shown in dynamic format that they used to be 2 PR places below the front page, now that isn't the case.
Articles in dynamic format never carry any green in the toolbar and so apparently show no PR at all, even when using the static url plugin.
So the benefits of using mod rewrite in your geeklog is glaringly apparent.
