Of all my web sites (I own about 30 of them), this blog is the fastest growing one, at least in terms of percentage of monthly traffic increase. A few years back I started this blog as just a fun outlet for me to write about whatever I felt like, free of any topic or format restrictions. I had no goals for it other than my own enjoyment.
Since then, A) my book was published, B) my other blogs have gained a lot more notoriety, and C) this blog has gained its own organic traffic. All of this has all increased the traffic here, turning this blog into an actual thing.
