@scottg - ah, now I see what you mean. Yes - we have made a few systematic changes, but these have been mainly in the timing and spacing of queries. We have also recenty changed the the AJAX API. We also used the SOAP API until it was pulled and we couldn't get new keys for new clients. I'm not sure how much detail I want to post on other changes we've done, but none of them are evil to Google and we do try to query as politely as we can by tightly limiting keywords/frequency and search depth (30).
