Twitter recently introduced topics, so that you can follow one topic that aggregates lots of tweets from various people. This is not what I want: I’d like to follow @JohnSmith, but only for the JS content.
As someone who tweets, I’d like some sort of kafka-ish topic queues: I would post tweets about JS in the JS queue, and tweets about Italian food in that other queue, so that people could follow the queues they want. In the end I don’t tweet on either topic because I’m afraid I’ll deceive people who followed me for the other content.
