I am curious if there have been any changes or modification to the WP site activity tracking SW. I have a one year old site, http://headmuscle.wordpress.com, and over the last 6 or 7 months I have been averaging between 100 and 200 hits per day. A couple of weeks ago everything plummeted overnight and, according to WP site activity tracker, I am now all of a sudden averaging between 2 and 10 hits per day. This simply does not seem believable. I would understand a gradual decline if I had not been posting, but an overnight drop to near zero seem hard to swallow.
There are several threads on the issue already, as you are not the only one having this experience. It’s even happening on one of my blogs while the other two are having consistent record highs. Staff is working on it, and I suggest you contact them to let them know whatever it is affects your blog as well.
