Weird story, but when I first used twitter ~2 years ago, it was to follow one specific current event, so my entire feed was one single-issue. I loved it! Over time I've obviously clicked on content on other topics and the feed got all mixed up with 20 different topics, which feels so gross and disorganised.
If anyone remembers 'Zite' app (which unfortunately got acquired and disbanded ~2014), it was basically a bunch of news feeds sorted per topic - super handy at the time for the things I was interested in: I could read 50 notes/articles on blockchain (then in its infancy), then on airbnb, then uber etc. I could read exactly one topic at a time without any distractions mixed in. It felt so organised. I really like single-issue feeds like what tweetdeck is (I think, I don't pay for it).
