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.
Aggregation itself doesn't necessarily create value, but depending on what is done with the aggregation can create much value.
Google news is a good example, no one could really say that having all that article discovery and grouping was providing no value. Google scholar provides no content by itself but is very useful.
