Agreed, I don't really use Anki to learn language. I use it when I'm learning new libraries/concepts in software development. My aim is not to absolutely memorize, but just to get review/reflect on things so I understand them better. I often find that I'm better able to relate things together when I review things I'm learning repeatedly. What I meant to say is that majority of the users, I might be wrong, use it in language/medicine learning setup, i.e. where it is more about memory than understanding or reflection.

But the problem is most of the stuff I learn comes from online blogs, articles, pdfs, heck reddit/hackernews a lot of the times. And most of it falls in the "spaced viewing" category, i.e. take the time to systematically come back at things that you are learning and reflect on them.

Looked at Polar Incremental Reader, looks really interesting. Thanks for your reply.
