Well, first thing that cames to my mind is that as an entomologist doing regular changes in the database, I ended up publishing a short article regarding a homonym that a friend spotted while browsing the site.
Second things is that, as an expert in phasmids, thepresence that we have here on the site is just amazing. As more and more phasmatologist have worked here, not only the ammount of records started to dramatically increase (people tend up to post more and observe more taxa that get identified) but it also resulted in a lot of new species and genera being recorded for the first time. In some cases we even managed to collect specimens and described them. This, and the obvious fact that having actual pictures of live specimens for studies and comparisons is invaluable. Most, if not all my recent work now uses inaturalist data to complement my findings.
