AO3 stat progress

There is *definitely* something weird going on with my AO3 stats; after uploading the new chapter of "High City on a Hill", I got 11 new page hits, two new subscriptions to the story (*very* nice; that means that people actually want to know what happens next), and... +19 kudos, all from guest accounts, with the proportion of kudos exceeding page hits going up over the course of the day. So not only have I got at least one reader whose page-hits don't register, I've apparently got about 50% of them, all wildly enthusiastic about the story...?

A 100% reader:kudos conversion rate would be improbable enough, but a 175% conversion rate looks decidedly fishy!

[Edit: the kudos is now up to +27 for +12 page hits, so something very queer is going on!]
