@thegibson regardless, I think one thing that's going to be interesting on the fediverse is how we build and support client apps. I think client developers should be able to make small incremental changes and integrate them into the rest of your social experience. That kind of ecosystem reminds me of the Facebook Platform, which was dynamic, chaotic, fevered, and weird. I wondered how other people thought about that era in social networking.
@thegibson another technology pattern that might be similar is the Greasemonkey one. WordPress plugins are somewhat similar, but usually take on bigger chunks of functionality than I'm thinking of, and of course only work on WP.
