LiquidPlanner: Sophisticated Online Project Management «

Web Worker Daily: "LiquidPlanner touts itself as “a revolution in project management.” That’s probably overstating the case somewhat (there are a lot of project management applications in the world), but it does offer a sophisticated feature set, including some things that I haven’t seen in other online project management tools. If you’re feeling constrained by the features of whatever tool you’re using, then this one is worth a look."
