Don’t throw away the context!
When it comes to music, images or video on the web, context is one of the most important pieces of information you can possibly get (next to the item itself).
Who posted/tweeted this piece of content? Where? Why? Those are all questions that context (like a URL to a blog/third-party site) answers for free! And plus, it makes you a decent web citizen.
And yet I repeatedly see sites that disregard it and either throw it away like Seeqpod (and sadly a number of other music-related sites) or do not give it proper importance, like the Internet radio indexer Onellama (they said “it sounds like a good idea” when I asked). The links are missing in their early beta, even though I’d argue they are a critical feature of their product (it REALLY IS important to link back to the web radio station which you are indexing and playing in YOUR site).
Context makes the things on the web more real & engaging. Why read, listen or look at something unless you know that real people somewhere are creating, organizing or discussing it?
I agree with Anthony. Context is king.
