Coinciding with the big change that removed the host crowding filter for some searches [webmasterworld.com], there seems to have been a significant positive shift in the Search Suggestions.
For the search terms I was tracking at least, no longer are there suggestions for "Company scam" or "Company ripoff" when there are no significant search results for those searches (thank you, Google!)
These negative suggestions were creating a reputation problem based on nothing more than search frequency. Google even lost a lawsuit in France about the practice last spring. To be clear, when there are published negative opinions the suggestion still may appear - and that's fine.
