>Ultimately, when I ask myself whether performance is more important than user privacy, I end up answering no. FWIW: In the past when I sold and supported these kinds of tools, users were completely anonymized - you saw them as "requests" rather than users. In fact, the best tools I saw didn't even capture "all" users, but rather did sampling based on various attributes, IE: request was outside the standard deviation.
