Facebook wants users' responses to improve feeds

-

Facebook it would emphasize user feedback when prioritizi­ng posts on the leading social network, the latest move to quell concerns over its algorithms.

The California giant said it would add weight to surveys asking users if certain messages are "worth your time" as part of its ranking process for its main news feeds.

"Our algorithm uses thousands of signals to rank posts for your News Feed with this goal in mind," said a blog post from Aastha Gupta, Facebook product management director.

"This spring, we're expanding on our work to use direct feedback from people who use Facebook to understand the content people find most valuable. And we'll continue to incorporat­e this feedback into our News Feed ranking process."

The move comes with Facebook and other online platforms under pressure over opaque algorithms which determine what users see at the top of their feeds.

Critics say these systems may be geared to highlight sensationa­l or divisive content, aiming to keep users engaged to boost monetizati­on.

Facebook in recent months has been de-emphasizin­g political content which tends to be more polarizing and moving to give users more control over their feeds.

In March, Facebook unveiled a change to give users more control over their News Feed and even to turn off the Facebook algorithm entirely and see posts in chronologi­cal order.

The latest tweak aims to use the surveys asking "Is this post worth your time?" to prioritize content in Facebook's ranking algorithm.

"While a post's engagement -or how often people like it, comment on it, or share it -- can be a helpful indicator... this survey-driven approach, which largely occurs outside the immediate reaction to a post, gives a more complete picture of the types of posts people find most valuable," said Gupta.

"Now we're building on these surveys by asking new questions about the content people find valuable as well as the content people don't enjoy seeing in their News Feed."

Facebook's move away from divisive political content gained momentum after the January 6 Capitol riot which was organized in part on social media.

After an internal review, Facebook acknowledg­ed that it failed to do enough to prevent the circulatio­n of the #Stoptheste­al movement that led to the violence.

"We took a number of steps to limit content that sought to delegitimi­ze the election," a Facebook spokespers­on said after a Buzzfeed report on the review.

"As we've said previously, we still saw problemati­c content on our platform during this period and we know that we didn’t catch everything."

Any type of regular, physical activity can improve your fitness and your health. The most important thing is that you keep moving!

Exercise should be a regular part of your day, like brushing your teeth, eating, and sleeping. It can be in gym class, joining a sports team, or working out on your own. Keep the following tips in mind:

- Stay positive and have fun. A good mental attitude is important. Find an activity that you think is fun. You are more likely to keep with it if you choose something you like. A lot of people find it's more fun to exercise with someone else, so see if you can find a friend or family member to be active with you.

- Take it one step at a time. Small changes can add up to better fitness. For example, walk or ride your bike to school or to a friend's house instead of getting a ride. Get on or off the bus several blocks away and walk the rest of the way. Use the stairs instead of taking the elevator or escalator.

- Get your heart pumping. Whatever you choose, make sure it includes aerobic activity that makes you breathe harder and increases your heart rate. This is the best type of exercise because it increases your fitness level and makes your heart and lungs work better. It also burns off body fat. Examples of aerobic activities are basketball, running, or swimming.

- Don't forget to warm up with some easy exercises or mild stretching before you do any physical activity. This warms your muscles up and may help protect against injury. Stretching makes your muscles and joints more flexible too. It is also important to stretch out after you exercise to cool down your muscles.

Your goal should be to do some type of exercise every day. It is best to do some
