I just googled "Shadowrun 4" while looking for the errata/FAQ for one of my players, and the actual www.shadowrun4.com entry was number 95 on Google's list. That'd put it on the tenth page of Google's default "10 results per page" search.
Doing just a search for "Shadowrun" even yielded www.fasa.com before I gave up trying to find the current official site on that list.
(and for the record, Augmentation probably shouldn't still be in the Upcoming Products section)
