As one goes back in time, the percentage of “needs ID” observations that are easy decreases (because they have already been ID’d) and the percentage of difficult observations (e.g. those with inadequate photos or other problems) increases, as does the percentage of observers who are no longer active on iNat to respond to questions or issues that need attention.
This is inevitable.
Obviously there are people who also look at older observations and find it satisfying to sift through the blurry photos to find those observations that are worthwhile, and there are ways to mix it up so that one is less likely to find oneself looking at page after page of observations one can’t help with (looking at observations in random order, or from a particular day, or by a particular user, etc.), but sometimes perfectly good observations just get missed.
How would you propose to address this?
