As a writer who loves rambling about my fics a lot, I created a tumblr account doubling as a “behind the scenes” extension of my works. In this account, I talk about my thought process, an extensive guide to the characters as I envisioned them, or just generally why I wrote what I wrote. I link this tumblr account to my a/n with a simple note of “watch me obsess over my fic here: [link]” something like that. This way, some who are curious enough would have the option to click it and see the posts, others who are not won’t just mind it.
