On SF&F, we have
[story-identification] regardless of media type (which I is my fault, but the community is against renaming). I would recommend using
[identify-this-thing] instead: identify-this-movie or identify-this-series. This allows users who specialize in one media type to only follow one of the tags, and users who like all media types can subscribe to
identify-*. The format is also consistent with identify-this-game on Gaming (on the other hand, Literature uses story-identification).
