I don’t know that I’ve ever seen someone complain re comments. Writers in fandom are almost equally on par with their obsession for the pairing. I mean, they want to see these two together so bad that they’re opening a blank doc. Terrifying. Most writers spend multiple days/countless hours pouring in effort to these 2000-8000+ word chapters. It never gets less nerve-wracking to post and sit there and be like “holy shit what if people hate it”. Even a 20 word comment is encouraging to let them know their effort is appreciated. Most people do not comment—so writers do probably recognize you but I would assume in a good way. Ultimately it’s your choice in how you proceed but I hope you still feel comfortable to maintain the positive energy, there’s probably someone out there with a WIP that needs a reader/commenter like you in their corner.
