Multichan is an indev textboard that can be a member of a federated network (servers share tags, threads, and comments) or stand on its own. It's easy to modify the program and its data, or to implement your own scraper / server.

Any ideas for where I should take this in the future? Two things I'm currently working on are Ayashii (tree view) and Futaba (thread preview) style board views, as well as textboard/imageboard scraper that stores data as JSONs and can export JSONs to Multich format. But I don't know what other kinds of features would be good to add in. No plans at present to add further javascript past the stylesheet setter and >>quote links..
