So I've downloaded the new version of DTV after I had significant problems with the previous version.
I've set the app to auto download the delicious/popular video channel. This type of tag-driven auto-creation of stations is really the way things will continue to evolve. When my genius friends can auto-add their favorite vids into my channel, and contextual ad wrappers from products, companies, or filters that I've opted in to appear along side the vids on my channel, we'll be getting somewhere.
I'd like to test-drive this service. But...I'm on a Mac. Maybe being able to try it out would change my first impression on moseying through their web site and doing searches, that as a stand-alone thing, this will go nowhere.
