Algorithm Changelog (ongoing)

there is a bug with trending algorithms in channels that cause them to be weighted differently than the new popular now (formerly popular 2). we’re working on fixing this and will post another update when it’s deployed

thank you for bringing this to our attention :slight_smile:

this should be fixed now (might take a few minutes for feeds to rebuild)

in preparation for a larger audience, we’ll be pushing an update to Popular Now that decays posts more quickly. the effects we expect to see are:

  • Popular Now changing more often
  • the “ideal time to post” being less important
  • the # of likes for items at the top of the list will be lower

we’ll post again when this change has been deployed

this has been deployed. we will look at this for a little bit and possibly make changes to increase or decrease the decay. we’ll let you know what we’re thinking once we’ve had a bit of time with it

we’re still evaluating the decay change, but we will be working on an additional change that limits the number of times a user can appear on Popular Now at any given time to 1. in the case that there are multiple potential posts by one user, the highest weighted post (e.g. the one that would be highest on the list) will be the one that appears

we’ve deployed the change that limits simultaneous Popular Now posts by a user to 1

here’s a clarification scenario on how this works:

  • you make a post and it starts trending so it shows up on popular now
  • later in the day you make another post
  • at this moment, your first post is still the one that shows up because it still has a fairly high weight and the second post is brand new
  • your second post starts picking up in popularity through followers, channels, etc
  • at the same time your first post is decaying because it’s getting older
  • eventually your second post “overtakes” your first post
  • your second post is now the post that shows up in popular now

Your Mix — which is currently an experimental feed — will be receiving a large upgrade a little bit after launch. this feed will utilize machine learning and act as a personalized recommendation feed designed specifically for you. you’ll also be able to subscribe directly to channels to more notably incorporate them into Your Mix. we’ll share more details about this second iteration of the feed once it’s ready to test

once we’re comfortable with the new iteration of Your Mix, we’ll be promoting it to a more prominent position in the Explore tab. we’re still working on UI treatments but will share more information on this as well as they come together

while we work on the Your Mix improvements above, we’ve decided to temporarily bring back Popular 2, with new rules. here’s how it will work this time around:

  • the top 1,000 current Popular Now posts will be randomly shuffled in this feed
  • the feed will be different for everyone and shuffled every time you load it

we’re going to try to deploy this tomorrow and will post another update when it’s done

Popular 2 has been deployed!

we’ve made a few large changes to explore today:

  • added Spotlight. this is a new section curated by our editors. we aim to highlight a wide range of bytes from around the platform and will update it every day :slight_smile:
  • renamed popular 2 to “new & trending”
  • moved popular now and your mix down the list a bit
  • moved latest down the list

we will experiment with these changes over the next few days

we’ve made a few changes:

  • popular now has been moved back up the list and lives alongside new & trending
  • for quality control and moderation purposes, for your consideration no longer pulls in brand new posts
  • “Your Mix” now loads significantly faster and scrolls endlessly. it does not yet filter out posts you’ve already seen or liked as you scroll, so they may pop up again, but this was already the case each time you opened it. we are working on adding the filtering functionality soon

we will be limiting the maximum # of people you can follow to 5,000. if you are currently following more than 5,000 you will keep who you are following but will be unable to follow anyone else until you go under the limit

we’ll post another update when this change has been deployed

the limit is now 5,000. choose… wisely?

we are planning two changes to rebytes:

  1. to mitigate general spamminess and misuse, we are introducing a limit to the # of rebytes you can do in a 24 hour period. subsequent rebytes will still “go through” but will only appear on your profile’s rebytes tab rather than going out to your followers
  2. to mitigate coordinated attempts to boost posts, rebytes that go out to a large number of followers will be staggered over time so that they do not reach everyone at once

we will share exact #'s and post another update when these changes go live

we’ve added a “thirst filter”, which will reduce the ranking of posts made by thirsty accounts in discovery feeds. we define a thirsty account as an account that is following an enormous number of people (in the high thousands) and has a terrible following-to-follower ratio. if you are worried about this change affecting you, don’t worry, it probably does not. this change is now live on some algorithms and will fully propagate by tomorrow morning

we are still working on the rebyte changes mentioned above and will let you know when they’re live

upcoming versions of byte will contain a new option on the main tab called “your mix”. this will live alongside your following feed. we are reusing the “your mix” name from the explore tab (which will be getting retired), but the algorithm is quite a bit different. here’s how it works broadly:

viewers

  • the first time you use it, you will see an assortment of different bytes from different sources (i.e. spotlight, completely random, previously popular, and more)
  • as you like bytes, the algorithm will learn about genres and creators you’re into and show you more from them, as well as bytes that are similar
  • it will also show you more “rare” or “unproven” bytes from new creators the more you use it
  • soon, it will also learn if you get tired of seeing certain creators and show you less from them
  • EVERYONE starts as a first time user, even if you’ve used the app a lot in the past. so it might take a bit of time for the algorithm to learn about you. you may see dupes in this case. please be patient :slight_smile:
  • even if you’re a brand new user, there is a chance you’ll see some dupes. we are planning to address this next week

creators

  • make good content that is properly categorized and it’s likely that your audience will grow over time
  • do not r4r, l4l, etc, unless you want a bad viewing experience for yourself
  • we are still working on refining the bytes that we show to brand new users because it currently does skew towards creators who were previously popular. we do this mostly for quality control purposes (unproven bytes have a higher chance of being low quality and new users are less likely to have a tolerance for them), but we are going to make it better
  • we will add a section to your stats screen in the future that makes it easier to understand how large your audience is

this is the first version and is far from perfect. we will be working on this algorithm for pretty much forever :slight_smile:

we discovered a bug in Your Mix that was causing posts from people you like to not show up as much as they were supposed to. that has been fixed and should be a bit better going forward

your mix will now incorporate new posts from people you’re following. it’s amazing!

we discovered two more issues in Your Mix that could cause posts from people you like to not show as much as they were supposed to. we are currently deploying a fix

the first rebyte mitigation has been deployed. to mitigate coordinated attempts to boost posts, rebytes will now be staggered over time so they don’t reach everyone at once
