No, not really. That's more of a standard web 2.0 approach to content, almost like Tumblr, from what I can see (likes and comments probably wouldn't be a thing in what I'm invisioning, for example, although following updates to the page probably would be). And I don't literally mean "Top 20 most popular whatever", as existing portals do that already, as it's easy to do a database query and order it based by views, or sales, or whatever.
I'm saying I currently watch like 15 different top 20 lists from a bunch of sources just trying to find the 4 or 5 unique items because they all tend to mention the same stuff except one or two things. I'm trying to find the more obscure or weird stuff that's still good, not just the most popular.
What I have in mind is where the focus is more on the connections between two specific pieces of content, that goes beyond a general recommendation engine and the connection can be based on many things. A tag doesn't fall under that category because it will just list anything that matches that tag (although a focus on tagging is at least better than what the Apple App Store has now, for example), and the tags are usually decided by the content creator, not other people who might see a connection that even the author might not.
I'm thinking more like on Wikipedia, where you read one subject, then on that subject you find a link to something else you're curious about, and go there, and then on that page you find something and go somewhere else, etc. The connections are community driven (each connection can be strengthened or weakened by the users), and the reason for the connection can be whatever is provided by the user that made the suggested connection.
Additionally, I'm thinking of using a metaphor more like exhibits in a virtual museum instead of 'hey, i made this thing, come look at it!'. The creator isn't necessarily the person who 'curates' the exhibit, or at least not the only person. Museum might not be a hip enough to attract people, so there might be presented differently, but the idea is a lasting place people can go to find out about that content and a bunch of links linking to it and from it from other content on the site for all sorts of reasons.
