Recently I have been wondering about the wealth of information that can be gleaned from the 2.5 million programming question on Stack Overflow. A few weeks back I found a tag trending tool, which can be used to measure the rise and fall in popularity of tags over time. Whilst this is a great little tool, I am sure there is much more that can be done with the freely available Stack Overflow data, for example, exploring the relationships between the many technologies people ask questions about.
