Ok, this was fun, going back through all my old bookmarks. :)
6. Recommend a fic that does something cool with format or structure (epistolary, social media, 5 things, non-linear, etc.)
I actually had more than a few options for this one. For example, there's a chapter in the absolutely classic fic These Games We Play by peacewish that is set to music. But for a whole fic that is done in a really unique format, I went with We Forget the Names Not Written Down by FourthFloorWrites. This author has done a few fics with really interesting and non-traditional styles, but this one always stands out for me. It's epistolary, and it packs so much meaning and emotion into its short segments. Definitely recommended for IDW Rewind fans out there.
11. Recommend a fic you think is a hidden gem/deserves more reads.
I went through my bookmarks looking for a fic that should have more hits/kudos than it actually does, and decided on this one: True Colors by ladydragon76. Ok, so yeah, it's got Bluestreak as the main character, which will automatically draw me in, but the authors characterization of him is what really sold me.
