I just checked trends again and they updated the similar search list. Before I had ten results including names of (I assume) non-famous people. Now I'm only getting three results: "itunes gift card", "borland developer studio", and "aperture review". That seems much more relevant than some random names and some Firefox search. I wonder if they added a filter to strip out names, to prevent privacy concerns. As I said before, it'll be interesting to watch this list in the next few days as it updates.
