Making For You pay more attention to your older likes

Common feedback about 💖For You is that it is too reactive to your most recent likes:

You can play with this parameter yourself in foryou.club/playground

I ran this change in an A/B test in For You for 27 days and it showed some positive results:

• 0.3% more users found something to like on a given day
• 0.2% more feed loads per user - more interesting content to scroll through?
• 1.1% more likes
• 2.2% fewer "show less like this" interactions
• though also 1.8% fewer "show more like this" - unexpected, but at the same time it is a very rare interaction and could be noisy; compare +108K likes vs -580 "show more like this".

Here are the full results:

I enabled this logic for all users of For You this morning and I hope it will make your content more diverse and interesting!
