Some people have been talking about putting explicit images of sexual activities on Wikipedia. Still images are being discussed just for now - but what about when we get more bandwidth and server space? Will some people also want to put on actual videos of these sexual practices?
Yes, a good modern online encyclopedia should almost certainly consider including movies. I seem to recall that Encarta had movies for some topic as far back as 1994. Things have changed somewhat in the past twenty years or so. The sale of the very successful sexually explicit educational video, The Lovers' Guide, through mainstream high street bookstores in 1991 under an 18 certificate showed that the general public is receptive to well presented informational movies on sexual topics. Obviously Wikipedia isn't a "How to" guide of that type, but where a movie would be useful and one is available under GFDL it should be considered.
