We've looked at a number of aspects of the weblog Boing Boing over the last little while. The topics discussed included things like posts over time by author, day of the week analysis, images/post by author, outbound links and acronym use. This continues our analysis by examining in more detail the contents of the actual posts. What are they writing about ?
The Radial Treemap shown below illustrates which topics from my simple topic hierarchy get more emphasis. This is scaled by the number of words written on the various topics. Posts which didn't match any of the topics very well were grouped under None.
Here are the first 3 high-level topics shown by themselves so more details are clear.
