It'd be nice to see an updated version of those that describes how those ideas and tools relate to a self/third-party hosting. The best I can tell, this is the model: My understanding is that each host has control over what they host and can subscribe to third party content filtering services to help do so. Then various indexes/aggregators (potentially third party) crawl hosts and provide services to find content. This is where voting or toxicity checks can be applied to manipulate reach. This content is also tag-able via third party services (and may be used by indexes/aggregators). The user is then able to select/configure indexes/aggregators and filter based on tags.
