Bluesky "For You" feed playground
This page shows recommendations generated by the For You custom feed. The algorithm has three simple steps:
feedle: Search and Discover Quality RSS Feeds from Thousands of Blogs and Podcasts
A search engine for blogs and podcasts, where every search is an RSS feed.

Quit social media that won't tell you their algorithm
Opaque feeds shape what you believe and you can never check whether they are working for you. We should insist on auditable algorithms, and support the platforms willing to build them.
From Feeds to Trails
To design the future of social media, rethink the interface before the algorithm.
Bluesky Post Statisticator
This will generate a CSV spreadsheet of Bluesky post statistics (number of likes, reposts, quotes and replies) from a given timeframe. All processing is done in-browser and no data is stored anywhere. It takes `(total posts / 100) * 0.1 seconds` to pull all your posts after clicking "Login". If it appears nothing to be happening, please be patient and wait a few minutes!
A quick guide to creating syndication feeds
RSS and syndication are the backbone of the web and have outlived many cycles of the tech industry. There's never been a better time to properly syndicate your content either, so Declan is here to give you a high level tour of your options.

The political effects of X’s feed algorithm
Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects1. Here we present results from a 2023 field experiment on Elon Musk’s platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects. Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users’ feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X’s algorithm has persistent effects on users’ current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.
