I honestly can't imagine what the feed looks like if you follow 1k people plus. It has to be nonsense at the millisecond level. The signal to noise just scales so badly. There just isn't that much interesting things going on in real time.
This is a cool idea but I am going for a walk right now and listening to an audio book. I am really looking forward to the walk and the book. A tail to keep the flies away I am sure is nice but to me it is just better to delete the flies completely. My walks are the most peaceful part of the day for me. There is no motivation needed if you get rid of the overexcited storm of nonsense from Twitter.
