I have seen an increase in Google referrals the last week. They mainly seem to come for second-choice keywords. The main keywords are slipping a little although not much. No time for definite conclusions yet but these referrals may come from the Something different section in the new Google layout.
@Brett: you have checked that your drop in Google referrals is not caused by members using the new site search functionality instead of Google to search in WebmasterWorld? At least I am not using Google anymore for site:webmasterworld.com searches and others may do the same.
