Data scoring techniques tend to change over time making past data inaccurate. As always, information here is for entertainment purposes only.

I’m glad you say this data is for entertainment purposes only… you are using Net Apps data which is so unreliable and very much skewed to a small subset of the US market.
I don’t want to sound like an ad so wont recommend some better sources of data but I think anyone that quoting Net Apps stats weakens credibility of the author. Most experts in the online field would know to get stronger data sets that the "popular" source.
Sorry Stoney but I think you should really look into your sources…. didnt seeing google 54% make you double take?

March 12th, 2009 at 7:01 amHi Stoney – With my comments above; I was not trying to say this is not actual data, or inaccurate in a pure number count sense. More that is taken from an unbalanced data set making it unreliable.
For example if I did a survey of 10,000 people in Louisiana and then one person in every other country in the world I could probably say "from actual data" NASCAR is supported by 90% of the world’s population… an extreme example but this is the point I was getting to with NetApps. The data set it is taken from is limited in scope and balance making the results weak.
I have an econometrics background so I tend to dig into these things more than I probably should
Also just wanted to say think it’s cool you published my comment criticizing data selection. I know loads of people kill these types of comments so glad you are someone open for dialogue
