It was a Kimalanche!
When Kim wrote his super-nice post about Chester (see next to last post on the page) and linked to my story, I have to admit that I checked my log files on my server several times to see if I could detect an effect. It didn't seem like there was any extra activity, so I kind of forgot about it. However, in the last few days I've been doing research for the Man into such arcane blogstuff as sitemeter and the ecosystem, so I thought I'd go look at my statistics again. I guess the updating takes a day or so, because now it shows a definite Kimalanche!
I've no idea why Sunday shows zero activity. All my Sundays look that way, so I suspect it has something to do with the backups that my host runs. I'm usually doing maintenance on Sundays, so I know there should be at least some activity! Anyhow, it looks like things are back to normal, so I guess I won't bother registering in the ecosystem after all ;-)
