i agree cuz i find it rather hard (sometimes frustrating) to comment on every single artwork i fave i've been doing so for months now, what started me was a stamp that said something like "i hate favewhores" & before then i only commented when i either had a question or if i had something to say & since then i felt kind of like i HAD to comment if i wanted to fave
but yeah, people should be more grateful that we even take any notice at all & this is just the stamp i needed to see
I would vouch for the opposite: A favourite is nothing compared to a comment. A comment means so much more. Now I don't demand a comment for every favourite, because that'd be unreasonable. But if people go around and fave stuff without commenting and feel proud for doing so, then I get upset. Upset to a point where I even compiled a list of rebuttals to all the reasons (at least the ones I've seen) people give for not commenting. If you're interested: [link]
I understand that a comment is better than a favorite but for me, personally, I would rather +fav than leave a pointless one-liner. I have more favorites than comments on my work but, again, I'll take that over a "good work" any day. A truly observational comment takes time and effort and like you said, some people are just here to look at art and collect their favorites.
