Do something useful.

usefulness = how much time it saves you doing some task ÷ how much trouble it is to use it

This issue can be rephrased as:

Be the best at something. Don't be too inconvenient to use.

fcc62fc has done a lot to get me closer to this milestone. I find myself using the original C++ Conception occasionally for some tasks, so it makes sense to port that functionality over (and be able to completely deprecate that codebase) before trying to do more.
