#DeepStash tries to be an alternate to algorithmic #SocialMedia by providing small bites of information from books, articles, and/or quotes. It has the ability to bookmark content, though it is limited for free accounts.
Alternately one can just screenshot the specific chunks of data and potentially make one's own filtered timeline if one combines the data from the screenshots into #Anki. This can either be done directly by using the images or one can quickly extract the text via #tesseract and some #python to generate a #csv file which can be used as an import into Anki.
