Good show. I checked your links on Maxthon [my IE without the IE baggage] and on Firefox (default browser with ABP add-on) for comparison.

1. On FF I have ABP installed, but there were no ads on Maxthon either for Ask. Is it due to "search bubble" or something else? Not sure. However, I too use uk.ask.com for my searches like you, so the 'bubble' should be the same for me as well. Hmmmm.

2. I got those two false positives also. But the rest of the search results were similar between both search engines (SO, rice.edu, stanford.edu, sourceforge, NVIDIA). I'll admit that I would have simply filtered those two anomalies visually and not given it a second thought. But wouldn't you say, search-for-search, the landing pages were pretty similar in the results returned (barring those two stupidities)?
