You can't learn to play basketball by using Anki.
Literally speaking, yes. You could learn basketball history, statistics, official rules, and maybe things like classifications of tactics or something via Anki, but not basketball itself.
More generically speaking, maybe. A few days ago I looked into the spacing effect on motor skills question : http://www.gwern.net/Spaced%20repetition#motor-skills I don't have fulltext for all the citations yet, but it looks like there's something there (even if it's not as strong as spacing effect on declarative memory or language).
You can play basketball well if you repeat a dozen core motor skills with high precision 10,000s of times.
It interesting to ask how you best spread out those 10,000 repetitions but I don't think that Anki helps with that goal.
There might be other motor skills were a high number of repetitions aren't central where SRS is more applicable.
I'm interested in trying to make better Anki decks for the LessWrong community, but I want to see how well I can actually do this first. There's a lot of knowledge out there about how to format and create decks, but it's still a decent amount of work, and there are lots of people who would benefit from Anki decks, but who wouldn't make them themselves.
In order to test my deck-creation skills, I'd be willing to do a summary + deck of a chapter or two of a book, then release them to the community for feedback.
I have two questions:
These links are fairly useful/relevant.

As a side note: I still do intend to do this, but have been fairly busy with the start of this semester. If there's no progress by March 1st, then you should consider this to be on indefinite pause.
