I've complained before that Pagans tend to underuse and misuse YouTube. Go to YouTube and search, for example, "Wicca," and you get a lot of slide shows with pictures taken from the web and some music (often peppered with a number of misspellings), or a self-made video by a teenager discussing what Wicca means to hir. There's nothing wrong with either of those (well, except for the misspellings), but the medium itself provides the opportunity for some much more valuable sharing of information, both within the Pagan community and with the world at large.
A group of local, DC Pagans have made a YouTube that does, IMHO, a really good job of showing how YouTube can be used: in this case to explain Paganism to the world at large. Kudos to the people involved for getting the framing mostly right. You'll notice, for example, that the Pagans in the video discuss in positive tones what Paganism means, how they practice it, and how it relates to other religions. They talk about the seasons, service to others, mysticism, relationship to other religions, etc. They never (thank the Goddess!) get defensive and state that Pagans don't worship the Christian Satan or sacrifice babies, etc.
If I can offer two small suggestions, and these are things that I think come with practice: when you're talking to a camera, look into the camera. Practice really can make perfect; this is a learned skill. And please use "religious communities" or "religion," instead of "faith communities." "Faith" is a central tenant of the three large Abrahamic religions. Most Pagans view ours as a religion based upon experience (ie, I worship Hecate and include her in my religious practice because I have direct experience of her, not because I take her existence on faith) and none of our Goddesses/Gods requires faith from followers. Discussing all religions as "faith communities" frames religions as being more or less valid to the extent they involve faith, which only helps the three large Abrahamic religions, not ours.
However, those are, as noted, small suggestions. In general, I think these DC Pagans are showing how YouTube can be a great medium for teaching others about our religion.
