I really disagree. Some call it "aggregation," but I'm starting to call this layer "discovery." This very site, Hacker News, is a filter that is mere pointer to content elsewhere. (There are occasional "Ask HN," but most every post posts elsewhere).

Most sites and tools I use every day are filtering tools. Techmeme is another great example.

It is true that a purely automated owl video scraper wouldn't be as good and one that was even cleaned up for five minutes a day, but that wasn't the suggester's point.
