Edit: once more, with feeling and links that work!
Hrm... well, you asked for comments...
This seems to be about American Wicca, not inclusive of British Traditional (Gardnerian/Alexanderian) Wicca... I could see a Gardnerian reading this and having a litter of kittens. But they wouldn't be likely to complain, what with the whole secrecy thing... ;)
One difference that might be mentioned is the philosophical difference in location of deity. Wicca usually believes that deity is internal (whole or in part), and Druidry usually believes that deity is external. Wiccan ritual is based on bringing out the deity within to enact change upon the world, and Druidry is generally focused on building relationships with the Gods 'out there' -- and will sometimes ask the gods for help enacting change, and will sometimes just be about saying hello. Wiccans don't generally do ritual just to say hello or to give praise or worship to the Gods.
Also, there IS a standard liturgy for Wicca, and it is stricter and more structured than the ADF outline. Gardnerian Wiccans (I think) still use it faithfully. It's the American traditions of Wicca, and the eclectic Wiccans, who have voluntarily abandoned the liturgy in favor of creative, syncretic, or eclectic ritual styles. But it does exist.
Disclaimer: I am not, and have never been traditional Wiccan. I called myself Wiccan until A) I found enough information about Hellenismos to begin practicing what feels like the best fit for me of all the traditions I've seen, and B) I learned enough about British trad Wicca to recoil and say "oh Gods, I've NEVER been that."

I don't know how you could write this to encompass the difference between Brit Trad Wicca and Wicca as it's practiced in America. They're such different animals. It's like the difference between Catholicism and Unitarian Universalists. The Catholics feel that the UUs are a bunch of hippy flakes who have hijacked the term "church" to mean something completely antithetical to what it meant in the good old days. The UUs think the Catholics are a bunch of severe, secretive old fogeys who do things by rote without any feeling and who should just stop complaining about the liberals and join the modern era. If you look at the UUs, you would be tempted to say that "churches have no set liturgy, unlike ADF groves." If you look at the Catholics, you'd be tempted to say "churches are much more dogmatic about liturgy than ADF groves."
I guess I'm saying that Wicca is a mess, and damned near impossible to talk about without pissing a bunch of 'em off. ::sigh::
