Apologies in advance but I have to get serious here for a minute about the subject of "being intimidated by fanfic authors." This is more con-oriented than Tumblr-oriented but the sentiments are applicable to both.
It makes me so upset whenever I think of all the times I went to a con and couldn't seem to find anyone to talk to. After being on a few panels where I made jokes about the joys of writing about dicks and butts, I would walk around, and it just seemed like folks were all doing their own thing, not inviting me to join them. I would always think, Oh, story checks out, everyone is put off because I'm a weird freak, it's just like in high school. Then I'd go back to my hotel room and wonder what I spent all this money for, coming here to be lonely.
Then, in the days after the con, I would see posts from other con-goers, or receive messages: "omg berlynn i was too shy to say hello at the con but i just want you to know that your fics mean everything to me and you're so amazing."
I really do appreciate those kind words, but...it would have been cool to actually hang out with you, you know?
One time I had the opportunity to chat with with a trio of folks who were the guests of honor at this con because they were screening their gorgeous and charming fan film, and they confessed to me that the day before, they had walked into a room, seen that I was there, and walked out because they were too intimidated at the very idea of being in the room with me. (So I sat alone and silent in that room for 20 more minutes.)
The thing is, even if I was the most popular fanfic writer in the history of the world, connecting with other fans and forming friendships is the only compensation I get. I don't eat better because you liked my fic. I don't get a swag bag worth $5,000 when I check into my hotel room at a con because I wrote that one omegaverse fic that everyone read. I do what I do and I write what I write because I want to be part of a community of fans.
But I should note that all is not loneliness and misery for Berlynn. I have had some of the greatest moments of my life making connections with people who actually did speak to me at cons. Sometimes it was just a hug and a few happy tears, sometimes it was deep philosophical discussions about writing dicks and butts while sitting on the floor of a party suite at two in the morning...but several of my IRL friends are people who were not afraid to just reach out to me after a panel, or say hello at the bar.
Here's how it might go when you connect with your favorite fanfic author: One of my closest friends is someone who was a big fan of my work, introduced to me by a mutual friend. Sitting across from me at a restaurant not too long after our introduction, this person had to point out to me that, whilst gesticulating exuberantly over my meal, I had gotten some macaroni and cheese on my sleeve. After that, they were not so starstruck anymore, and now we live in the same building, which makes it easy for us to hang out and giggle over old TV shows together a couple times a week.
Probably there are fanfic writers who don't want to be bothered, who don't want to be messaged, who aren't in it for the social connection...but they are not the ones following you on social media. They're not the ones with their inboxes open, anonymous messages on. And they're not the ones strolling through the common areas at cons looking for an empty seat at a table.
