One thing I really, really would like is the ability to download the identifications of particular users (i.e., if there is an expert in a certain group that I know is credible, I would probably take their ID over the community ID in any project that I wanted to use the data for).
In my mind, this would essentially solve the ID quality problem for me or at least give an important workaround. For example, anytime I needed Euphorbia data, I could use my ID or the ID of one of the other Euphorbia experts on iNaturalist and be confident that the data I was using was expert reviewed and actually research grade. This doesn’t solve the ID quality problem for GBIF, but would be a major step towards making the data useful.
