Youtube is so great. The videos are getting nicer as high definition camcorders become more affordable to the average consumer and people are getting better at using video editing software. Also since Youtube started sharing revenue with video posters(youtube partners), there's a huge monetary incentive to build channels with high quality content. You are seeing lots of high quality channels being developed all the time. I hope some of the people viewing these videos might get inspired to try setting up a planted aquarium, reef tank or a tank with a type of fish they've never experienced. Maybe others will start a youtube aquatic channel and spread their fish knowledge via video to the world.
