NASA Pictures Of The Day | Self-populating binboard
Funny Tube | Self-populating tube
Game-World Videos | Self-Self-populating video magazine

That could be mainstream or adult - the niche just doesn't matter. Maybe their design is no perfect, because there are very old and not best templates (I have to find some time to re-design them), so they just a proof of concept and nothing else.

P.S. No I won't show off my actual commercial networks here
