I'm still not sure what to make of the new system. I don't feel particularly inspired about it ATM TBH. I've largely been avoiding the platform until everything calms down a little. The dust needs to settle before any proper analysis of where HF21 has 'worked' - however we measure that (if that was ever decided, I don't think it was).

My curation efficiency is currently 70% btw, that's guessing at the optimum times post HF21, so it could get better. I'm quite good at curation efficiency but not the best. So <50% = room for improvement, then again it might be different with your huge SP?!
