I use it for all sort of things:

* Vocabulary in different fields

* Concepts in maths, physics, comp.sci.

* Geography

* People I want to remember (both historical and more distant relationsships)

* Some useful numbers (e.g. visa card number)

* Silly things (like the periodic table)

* Programming languages (syntax and similar that I might otherwise forget, and useful standard libraries and third-party libraries)

* Useful tools and ideas/concepts I want to remember

I make my cards atomic. No long answers. And I avoid having a large workload - I add new cards at a rate such that I review about 60 +- 30 cards per day. It takes me ~15-20 minutes, and I find it very much worth the effort!
