A guid NY to you.
Yes, I look in regularly but have posted relatively few observations on iNat, mine are mostly holiday (or course abroad) spots, but a few are UK. iNat is not so much about learning for me. iNat's thumbnails are easier on my eyes, and the photos seem fast to load. But there is a relative dearth of community, I think, compared to iSpot.
There is not so much dialogue on the site. https://www.inaturalist.org/observations/9056019 was one example for me, but even in response to a question sometimes there is little in return eg https://www.inaturalist.org/observations/8930151 - but maybe that's unfair? INat's auto ID when putting up an observation seems impressive to me, though see https://www.inaturalist.org/observations/8467816 for comment on the auto ID suggestion given for that observation.
I agree, the highlighted posts are inspiring, with wonderful quality photos like this week's bald eagle and merlin. That NZ lichen, though, is amazing in both photos, great stuff.
