I do this all the time. I see so many brainless, low-effort posts all over the internet that I don’t want to add to the pollution with anything I’m not confident is either informative or funny.
But I also want Lemmy to grow and thrive, so here I’ve been making more of an effort to try to finish and post even comments I’m not so certain about. I figure that has to be better for the site than contributing nothing at all.
