Hi all....thought Id throw in a few cents here too
DDave...its definitely nice seeing them go after the dynamic stuff....some of the limitations Ive seen so far are passing more than two variables after a cgi? statement and passing session unique parameters such as a session id...those seem to throw the Google spider a big roadblock...but since they are just getting into this end of spidering Im sure they'll get better.
Got to agree with the freshness aspect too.....seems the fresher content you can get out there the more you get visited in my experiences.
One othere thing that goes along with this is to make sure that cgi you dont want spidered gets protected in the robots.txt as Google loves to go after every link it finds
