YouTube, the online video Web site that rose to fame by making it easy to view the best videos created by others, is, according to this downloadable podcast, upset with Bestofyoutube.com, an aggregation site and podcast run by Lars Thorn. Why? For making it easy to view the best content on YouTube as a podcast. YouTube, which stubbornly claims they cannot properly filter out unauthorized videos, now says they also cannot verify if their users are okay with Bestofyoutube.com repurposing their clips. Of course not. And really, is that YouTube's responsibility? No.
