For me, while I can't induce an LD at will, just intending and trying has increased my frequency from once every few years to a spurt of them once every few months.
However, I've found that it's taking some experience "working" with them. At first, I really couldn't do much with them at all, except pretty much play by the rules of the dream with some awareness. However, as I've done it more, I can start to manipulate them. One time I tried a dream interpretation while in the dream. Another time, I tried to change the scenery completely. The dream interpretation worked wonderfully, but changing the scenery completely didn't work so well, until the dream started to end.
