I would like to see (and this is a pie in the sky), that anyone wanting to create a platform like INat, first look at what is out there. Instead of re-creating the wheel, add their funding in to improve the wheel.
With a platform like INat (or equivalent) where it allows you to customize so much, it could easily be used for just about everything.
From what I have seen on this platform the INat team would look at any way to improve this site, and accommodate other fields of interest.
This would assist in pooling resources for the greater benefit of all users, both amateur and professionals alike.
