Garter. The first stitch you learn. The simplest of all the stitches. Boooooring, right? Not if you do it right.
I'm starting to see a revival of this simple stitch, and I'm quite excited about it. While I'm not a overwhelming fan of working this stitch myself over large portions of a pattern, I feel it has a very solid place as a design element and I look forward to seeing how far this resurgence goes.
