There's no question; 2009 was a slow year for blogging for me. I posted only 142 times during 2009, the lowest annual total in my blogging history.
I averaged just 11.8 posts per month in 2009. The most active month was August, when we traveled to Hawaii and had lots to write about. That month I managed 22 posts. The slowest months were April, October, and December, in which I posted only seven times.
By contrast, my chattiest year was 2005 -- my first full year of blogging -- when I posted 272 times. Looking back at that year, though, I think it is safe to say that many of those posts were short and externally-referenced -- links to other places. This is the sort of thing that I now handle with posts to my Twitter account or to Facebook.
I've started an effort to try to increase my blogging this year, but we'll see.
