Quick updated thoughts on niche quality control.
Here is the state of play of the upvoting/downvoting.
Niches in approval process: 72
Niches that look like they will be rejected: 6
Projected rejection percentage: 8.33%
That seems really good to me: we're getting over 90% success rate with niches proposed at this point in time, and that's with people being quite strict (and appropriately so in my view) in terms of standards.
I think a few things are going on that have contributed to this success rate.
1) The community has learned a lot about both suggesting niches, and voting
2) The standards set by the voting are almost certainly helping motivate niche suggesters to be careful with their suggestions.
I would guesstimate that out of these 72 niches, maybe 2 will be approved that have problems that will require resolving (beyond typos) down the road. That's not a terrible outcome, considering we're human and fallible.
So my conclusion is - I don't think we're being too strict with our voting, and the system is for the most part, working quite well. Better than I thought it would, to be honest. Once some of the systemic issues are addressed by the Team, I expect things will only improve from here.
