The alt-development by www.participatoryculture.org is looking good but is somewhat stalled from bugs and feature creep:
Is the democratic sieving of internet video – it is a good idea and functions – but the needs to be versions that concentrate on different subjects otherwise the soft porn and comedy will dominate and hid more in-depth content. Currently I don’t think it is open sources so people can’t use the code base to do there own version.

Problems with soft porn and lack of substances to most channels, the idea of RSS feeds being traditional TV channels isn’t really working as the just isn’t anufe content to fill a secdual on any one channel – so the need to be a playlist generator which takes all the different channels and creates with a templated traditional TV look and feel.
