TV Tropes is an excellent site that provides an entertaining service - as well as one that's likely very useful to authors, game designers, animators, and any other media creators - for free. I like to browse TV Tropes whenever I need to kill some time, or when I want to see what my favorite games and shows look like through a more analytical lens. I've added some images of a TV Tropes page to illustrate how pages for popular pieces of media tend to look. (However, pages for less well-known works tend to be smaller simply because there are fewer people working on them, so keep that in mind.) In summary: Yeah, it's a good site. It does what it was made to do, and it does it well.
