Twitter has changed its policies such that it is now putting tweets into your timeline based upon who you are connected to and what they feel is relevant. The algorithms for relevance are a mystery, however.  The official explanation can be found at What is a Twitter timeline? It sounds like Twitter’s new paternalism.

Daniel Graf, Twitter’s new product boss, put it this way:

Surfacing the kinds of great conversations that pop up in peoples’ timelines from time to time, making sure that for those users who follow hundreds of accounts, they don’t miss the very, very best pieces of those streams as they flow by, and then…for those users who are new to the platform and are coming to the platform for the first time, getting them value immediately.

I don’t care what Twitter feels is relevant. I’m capable of building in the necessary serendipity that I need for the human signal that works for me.

The fact that Twitter is going to impose its big greasy Silicon Valley fingers on my carefully polished lens represents, I fear, the beginning of the end.
