POPSWolframAlpha and True Knowledge I tested WolframAlpha and True Knowledge today. I found both very impressive they both gave me correct answers, Wolfram had a few problems but most probably because of traffic to the site They are not search engines, Wolfram computes answers not stock answers from a database but on the fly , True Knowledge had a more polished feel to it but I guess it has been around a bit longer.
