Hi all, I started experimenting with this new approach to finding valuable content online after I got frustrated with traditional recommendation systems leading to echo chambers and all sorts of other nasty failure modes listed in the write-up. Unlike traditional recommendation systems, the lexiscore uses a language model which has access to your written notes. It estimates how surprising different content items are for you based on the model's perplexity in reconstructing the texts. This way, you can quickly tell which articles are likely to be too boring or too challenging and narrow in on the sweet spot of balanced skill and challenge.
