Is very vaguely categorising helpful at all?

@cas4moss

is this helpful? On the one hand, I’m guessing any identification is better than none, but… would this stuff get categorised more specifically just as easily if I did nothing

Yes. It is helpful, and encouraged. There is a discussion here about etiquette in making identifications that might be helpful to you-- https://forum.inaturalist.org/t/identification-etiquette-on-inaturalist-wiki/1503. Watch out for placeholders (discussed in the cited thread).
