Do you already know Google Trends from Google Labs? Using Google Trends you can see trends of keywords Google users are searching for, how much the keywords appeared in news article headlines and where over the world people have the highest interest (more...).I did a comparison of favourite distributions and the result shows a clear trend towards Ubuntu, while the interest in all other distributions declines. However please also note that this might also indicate that a lot of people use Ubuntu and have problems with Ubuntu and are looking for help. Personally I believe its a combination of both. First there is a high interest. On the other hand there are excellent resources for Ubuntu and people know that Google is of great help for Ubuntu problems, while I wasn't able to get so much help from Google for SuSE problems in the past.
Google Trends comparison for various distributions.
A big surprise was the regional results. Italy is the clear leader in searches for Ubuntu.
