I've used Anki for years to learn Japanese. It made learning to read relatively painless. You do need discipline to get far with it though. I managed to get my vocab deck up over 10,000 words, but leaving it for even a week is difficult.
As far as language learning goes, you also need to realise that no amount of SRS'd words is going to make you a natural, fluent speaker, so don't fall into the trap of spending all your study time reviewing.
