Great post Chris_R
In some industries/segments even frequent updates using Freshbot info won't change SERP's.
Example the client I am doing SEO work for- _all_ the other sites in thier industry have been the same for over 1 year. All static sites.
That's why every update thier site is the only one to move up. :)
Last update for 'industry name' company they went from 23 or so to #3. Now even with this update they are still at #3 for that phrase, and have gone from #34 to (as of now) #13 for 'industry name' which is their big phrase.
This industry is only known by a couple phrases...and all static sites- so my point is that even frequent updates wouldn't change the SERP's for this industry.
The deepcrawl and links with anchor text is the key in the above case.
So, if Freshbot could apply new links hence PR THEN things would change really quick.
But- doubt that will happen. Too much room for abuse and too much computer power needed...not worth the efforts...
