I don't really see much use for Anki for everyday life, honestly, because I don't have too many things I need to memorize right now.

However, some people at the LessWrong DC group have started learning Lojban, and Anki is just the biggest possible stick to hit the "learn words in a new language" problem with. I've learned a lot of words just doing that for a week. I still have to learn grammar concepts, but having a bigger vocabulary at my fingertips is pretty great.
