&gt; and an algorithmic timeline<p>I&#x27;d be reassured about algorithmic timelines if Twitter&#x27;s attempts were not so terrible.<p>A year ago I started following Bob (an Internet famous personality.)  Bob has made one post to twitter, and I&#x27;ve forgotten that I&#x27;m following him.  Until one day Twitter puts a post from Ann - a friend of Bob that Bob follows - into my timeline.  Ann and Bob post exclusively about eg Minecraft.  I post and read exclusively about mental health treatment and stigma in the UK.  I immediately unfollow Bob (because he never posts anything and I&#x27;m not interested in anything people he follows posts) and I dismiss the post and say that I didn&#x27;t like it.<p>And Twitter will do this week after week after week. It&#x27;ll post something to my timeline that my twitter account is clearly not interested in.  (High end bicycles; alcohol ads; cars; etc etc).<p>I wouldn&#x27;t mind if it was purely random - &quot;hey, we&#x27;re going to show you random shit and maybe you&#x27;ll like some of it&quot; is better than &quot;hey, we think we know what you&#x27;re interested in. We&#x27;ve spent time and money developing these algorithms. How about Pianos? Cod fishing? Teaspoons?&quot;
