<i>&gt; maybe your interests have changed, so when you check your timeline its like listening to those old mp3&#x27;s from the 90&#x27;s that you still keep around (not your current tastes, and terrible encoding rates), so now you need to curate a new timeline, and that&#x27;s a lot of work, and where to start?!?</i><p>Lists could be used as forkable alternate universes, but Twitter does not provide the tools.<p>- keep high and low frequency users in separate or topical lists, keeping in mind that people may change tweet frequency<p>- create annual (past you, future you) lists and fork  each year, removing people or topics that are no longer aligned<p>Instead of Twitter black box curation that cannot possibly serve the millions of niche threads and communities, Twitter could enable 3rd-party analytics for refactoring lists&#x2F;streams by metrics that are under the control of users.  Even the curation signals could be crowd-sourced on Twitter itself, with appropriate API support.<p>Twitter could have an API competition to re-engage 3rd parties.  Use the raw datasets already available to academia and identify  new signals and APIs to enable client side, human &quot;intelligence augmentation&quot;  innovation in curation analytics.  As a side effect, curation will provide new signals for targeting.
