In short, they have acknowledged that it can be extremely frustrating if your news feed gets jumbled during live ebents like sports matches and during TV shows. The old algorith meant that the age of the tweet was one of five contributing factors. So, you could for example see a story saying that your team were winning 2-0 and then scroll down to find they actually lost 2-3.
They have now added two extra factors into the algorithm (previously they included the popularity of the poster, the popularity of that tweet, your personal interest in the poster, how recently it was posted and the type of post - favouring visual posts like video clips). Now, they will also take into account:
- trending topics (whether lots of people are also talking about the subject that your tweet is focused on at that time) i.e. during a big football match, if a goal is score, lots of people will be talking about it, so the post is more likely to be seen at that time.
- they ave also adjusted wjat they mean by interest in a post. Previously it just looked at how popular a post had been with other people who had seen it. Now that has been adjusted to take into account when they saw it and reacted, promoting the posts that have been more interesting, more recently
I think these changes are logical and helpful. It shows that Facebook is listening to their users and is prepared to adapt when they make mistakes.
