Now available is Part 2 of our Web Tech Report 2011 data mining project. We have compared the results of the most popular web technologies of the Top 1 Million Web Sites with the most popular Technologies in use by the Forbes Fortune 1000 US Corporations.
There is a clear preference by the largest corporations to build systems around proprietary technology, as opposed to top million where the preference is for open source based solutions. See the full reports for details.
See the following chart for a comparison of our numbers comparing the results from the Alexa Top 1 Million Survey, the results from this report and the results from the ongoing web server report from Netcraft.
