Random Wonderfalls reading

I’ve been watching Wonderfalls lately. I missed it in its run because I didn’t have access to a Fox station, but bought the DVDs on faith in Tim Minear (near as I can tell so far, Tim got called in to tune up Bryan Fuller and Todd Holland’s idea). I got to wondering about which of WF or Joan of Arcadia came first. According to this article, " The two shows were developed and sold to their respective networks at the same time, but the September debut of Joan of Arcadia and its status as one of the season’s few hits make Mr. Fuller and his colleagues seem like laggards, or worse, copycats."
Also of note in the article, JoA creator Barbara Hall comes off as an asshole and a bit dim: "I don’t see Joan of Arc anywhere in [WF]." And hidden in the middle of the article, where Holland and Fuller are spit-balling series pitches, "How about Rosemary’s Baby, all grown up and fighting the evil within?" Now where have I heard that before? Finally, I can’t figure why the article claims Tim wrote for Buffy.
