Creating videos, let's be honest, is a pain in the neck. But showcasing OTHER people's turns out to be pretty simple with tools supplied by Magnify.net
Launched yesterday at the DEMO show in Palms Springs, CA, Magnify.com members can create a website in seconds and, using search terms in an easy interface, they can "acquire" 100s of videos from YouTube, Google, and other sites in just a couple of minutes. It's all free, and is intended to build communities around highly specialized interest areas. Visitors vote on videos, and review them. Again, all free.
Here's a example site I built in just a few minutes.
Now, let me clarify a few things. First, these sites don't actually "host" anything. The videos stay on YouTube, or wherever. The videos you get using the search tool probably aren't all going to match what you expect, so you will very likely have to do a lot of weeding to get rid of the junk.
But it is kind of fun being your own TV "producer," even if you don't get the big office and couch.
