@3MMA I can't quote you for some reason, but I agree completely. Back when I first started posting fic way back in like.. the late aughts, critique was so common that just getting a comment that said "This was good, I liked it!" was a huge surprise. My first fics got criticized pretty harshly, to the point where I took them down, but in retrospect I'm glad it happened. I learned a lot. Especially about what not to do.
The days of concrit aren't completely dead, though. I do still occasionally get critique on AO3. I suppose it's possible that I've personally garnered a reputation for being chill with it, since I'm fairly prolific in my chosen fandoms and therefore lots of people do at least know of me. But I think it might have more to do with the particular fandom. Seems to me like the older a fandom is, the more likely you are to still get concrit - I guess because older fandoms skew older in terms of the average age of the people reading the fics?
I may be off entirely, though. The only fic I've posted in years that actually revieced more than one critical review was a single fic where a lot of readers didn't really like the ending.
I think that growth takes time. My first experiences with hardcore concrit were humiliating. Once I got over myself, I realized how much better my performance became through that critique. I learned this lesson in a very hard way, in a different medium. I applied the lessons to writing, & it made my ability grow. Currently I’m not able to find the exact words I’d like to describe these lessons, but they were basically about humility & growth. Something about how you can’t add more water to a cup that is full. If you think you know everything, you learn nothing.
I’m noticing a resurgence of concrit on various fanfic archives. Slowly but surely & outside of any one fandom. Overall, I've been seeing minds changing, writers growing, & not being so fearful of the various aspects of growth.
Older fandoms
do seem to have more in depth discussions going on in the comments sections on Ao3. I think part of the backlash towards concrit in fanfic communities started to get bad during the
dark times of tumblerites & SJW’s infiltrating every type of online community in existence. The stage was set by about 2010, and the BS mindset only grew in popularity. I noticed it as a real attitude problem by about 2020, maybe earlier. By then, it was clear that something had gone terribly wrong with a core part of fanfic culture. I remember seeing very popular twitter posts making the rounds that lambasted anyone who dared say anything beyond “
nice story, loved it,” that went on to declare concrit as a terrible evil. Of course there were a few voices of reason & wisdom, disagreeing, but takeover had already occurred. Luckily, nature is healing, as it does. Slowly but surely, those who write, & take part in writing, reading, & reviewing on fanfic sites, are embracing the ignored wisdom of the past, for themselves. Each writer who realizes that they’ve grown stronger as an artist due to concrit, is a victory in the direction of growth.
More comments tend to be given to works that challenge readers. I’ve noticed that too. Even during the extreme SJW-etiquette heyday which we’re currently living through, human nature is just like that. What many miss is that it’s the height of compliment to have your words recognized by another, so, the writing that works others up so much, has really touched them. This is part of why concrit is such a gift. I’ve noticed people tend to comment more on what they dislike, more than what they like (myself generally included.) I do my best to balance my criticism when possible, & also discuss what works in a story. Kinda had to get used to doing so more in the current day & age, to even attempt to get the message through. There is something wonderful about being able to discuss things with full honesty, (respectfully of course,) while not having to walk on eggshells in fear of an adult baby tantrum.
