Today someone suggested me an idea for a potential extension of existing CritiqueBrainz functionality...

One way we could make CritiqueBrainz more useful and interesting is by providing reviews for music, places, and other things is by aggregating reviews from other sources. This is a nice way to provide access to different perspectives from different authors, in addition to reviews that we have already. Even better when we don't have any reviews of our own.

This is useful particularly in cases when we can't "import" reviews (like we've done with BBC Music ones), because they are not distributed under an open (CC) license. But what we can do is provide a link (perhaps with additional info).

So something like Google News, but for reviews (of music or something else).
