>>359736Booru is another imageboard software family, but more geared toward cataloguing images for long-term storage, whereas the Futaba software that 4chan uses is based around temporary sharing and discussion. The main advantage to boorus is that they have extremely flexible tagging systems that allow for powerful and specific searches. Boorus allow support for essentially unlimited tags, so you can get very specific ones if enough people support their use. Furthermore the search engines used by boorus allow for advanced multi-tag searching using boolean statements, which gives users a great deal of power in finding exactly what they want.
However this system depends very heavily on having a large and active tagging community that adheres to a single standard, or else things can spiral out of control.
