Simplenote was my favorite note taking app until it lost notes of mine a few years back.

I decided to give them another chance recently--hoping that these syncing issues had been cleared up--and Simplenote lost even more notes. It hasn't been dependable at all in my experience, and that's a shame because I love the interface and its focus on simplicity.

I'm excited that parts of it are going open-source. Hopefully the server will be made open so some of these core issues can be addressed.
