The other day I needed a tool to build quickly a site and wanted to know which one would cause me less trouble.
I decided to start googling about things like "drupal nightmares", "wordpress is driving me nuts" and things like that, and use the relative number of search results to decide which one to choose.
As the process of doing it manually is not very enjoyable I have built this site that uses this same idea. It can be entertaining to search whether Lenin or Stalin is preferred, discover that Romney is more hated than Obama, or that, coming back to my original query, I should use drupal instead of wordpress.
The site is here: http://www.hateratio.com
The current hate algorithm is pretty simple but gives acceptable results. I can improve it but I'm not sure if this site is of any real interest, or if there are existing and better options to do this kind of comparisons.
I'm using Bing instead of Google since the latter does not allow this kind of usages AFAIK. Doing some tests, I found Google results to be more consistent, but Bing's are good enough.
Let me know if you have any suggestions. I hope you like it and find it useful, or at least entertaining.
