I just rolled out a major bug fix to Digest on the web. There was an issue that caused some topics to appear incomplete, missing many stories that should have appeared.
If you are using the web version, you might have not noticed this even happening, but now you should find the topics are doing a much better job. This is especially true of custom topics.
This bug did not affect users on the iPad.
I’d like to also take this moment to say if you are a Digest user and are finding certain items or topics not performing as you expected, please reach out to me. While Digest is in beta, the best way I have to improve the algorithm is working one on one with cases where you find room for improvement.
