Of course they are. One of the beautiful things about the Web is that it's easy to organize complainers, I mean demonstrators. A Flickr group brilliantly named
NO VIDEO ON FLICKR is protesting the new ability for user to upload short video to the site. Why not? I know I hate when a really useful, free service tries to enhance my experience.
The group worries that Flickr will become another YouTube and bring with it all the terrible, grainy, offensive and meaningless video. Of course, you can always filter video out of your search results in the settings area - but still - how dare Flickr try something new.
