Nice article. Like Nielsen, you seem to have discovered Incremental Learning for yourself.

If you want the whole package in software (i.e. not only the SRS part) give SuperMemo a try :)
I don’t want to make this into a big internet argument but an explanation is in order I think. My account is incidentally also only a few days old so I won’t be mad if you think I just created it for the upvotes.
This article made the rounds in a community. I strongly suspect many of the members upvoted piwos comments. I am pretty sure there were no VPNs etc. involved.
