I am always amazed by the power of communities of practice. An e-friend of ours (Gilmar) posted a querry on our virtual community ( Learning With Computers ) asking for hints on video maker site. Some members (Ana Maria and Bob Palmer) suggested Stupeflix. I tested it and loved it. I created a channel called teacher stuff and seached the tag teaching on flickr and twitter and this was what I got. Nice, isn't it?
