One nice consequence of the move to WordPress was a tidy set of data about my posting history, organized by months, from my first post in April 2003 through September (not yet complete of course). It’s currently on the sidebar on the left (though i’ll probably get rid of this in the layout: it takes too much space, and the links aren’t quite right anyway). Here it is in the form of a sparkline instead: 
A few details are obvious:
- Typical initial blogging enthusiasm resulting in lots of posts (blue dot: high of 41 in June 2003), waning down to the first zero-post month (first red dot) in July 2004.
- A definite seasonal effect: summer has generally been a quieter time (the second red dot is zero posts in August 2005), and the two peaks after the decline have been in winter (Jan 2005, 12 posts; March 2006, 18 posts).
- The blue zone is 1 standard deviation, and i’ve been there consistently since about 12 months after starting
Since i have the exported data in a tidy text file, a little parsing would let me create a parallel graphic for length of post, hopefully a little more consistent over time.
Other resources on sparklines:
- Background on sparklines from Edward Tufte
- Bissantz provides several nice tools for making sparklines, which i used to create this graphic.
