Troon, to my recollection, Michael said submitting to G was a no-no.  But what about pinging our sitemaps to places like pingomatic or pingoat?  I don't know if that was discussed, but it seems like it would get spiders coming.

Michael, if I remember correctly, you said before that something changes on our sites for every spider visit so it appears like fresh content?  If so, what changes?
