I was scanning the Wikimedia mailing lists and was happy to see there was a wikistats list! I've subscribed so I can keep up-to-date with things. I saw there was a thread in June about WikiApiary. I'm the one that created WikiApiary and continue to work on it in spare time, along with many others that contribute new sites and such. I just wanted to say Hi.
Also, I just created some email lists for WikiApiary as well so if you are interested in subscribing to those you are welcome to.
