Hi! I'm Tabby (not my real name).
I've been on this site for a while, but I've yet to post anything. Maybe one day, but for now I'll settle for lurking.
Feel free to peruse my favorite's list; there's some great stuff in there that could use more recognition. I'm currently trying to review most if not all the stories I read in the future in an attempt to inspire the writers and show support. I highly encourage you to do the same. Tell them what you liked about the story--the witty dialogue, the symbolism and foreshadowing, the plot twists, the clearly researched world building that probably sent them on a four hour Wikipedia rabbit hole about sheep herding in the fourteenth century--just let them know you appreciate the work they're doing and you're excited for what's coming next.
There are a handful of stories I'm really into right now that I think deserve some promotion, so here's a short list:
The Avengers: A Man's Word by GoAskAlice137 stars one of my favorite teenage OCs (who isn't annoying! She's actually really well written and has a great character arc! I'm serious!) in crazy but completely believable Marvel Madness fashion. The protagonist is relatable and well developed to the point that you cheer her successes and scream profanities when somebody tries to mess with her. I often found myself caught in the story's emotional waves and experiencing genuine powerful distress and joy along with the main character. The emotional writing is effective and direct, so it's a great way to connect with the character quickly and easily. She's relatable, admirable, and best of all real. She's got a good balance of flaws and strengths with a realistic personality. She feels like a real teenage girl caught in an impossible situation, but one you actually like and want to see succeed.
Walk Two Lifetimes by Coolio101 is quite possibly the best self-insert I've read. It's a med student reborn as Hisana, Rukia's sister and Byakuya's wife. It's an ongoing epic, so while the beginning might be a little slow it builds into a marvelous story of character development, relationships and interaction. The protagonist is unique and incredibly well developed with a believable but still dramatic plot (c'mon, it's Bleach). If you like sass battles and tiny healers outwitting and trash talking people twice their size and ten times their age, you'll love Hisana (seriously, she's badass. I adore this chick). It's inspiring and uplifting, but watch out for emotional trauma and moral dilemmas.
Sanitize by Sage Thrasher is another excellent SI/OC of a woman with medical knowledge being reborn into the warring clans era. My favorite is the world building, with lots of literal building of cultures and societies in the middle of a war zone. The characters themselves are both secondary and vital to the story itself as it focuses on one healer's life spent navigating shinobi conflicts while trying to make the world a better place (the protagonist has the best tendency to both fear shinobi and Not Put Up With Their Shit and I absolutely love it). The focus isn't really on the characters themselves, but more their role in the progression of the world and the writing of history. I found it a refreshing change of pace after reading mostly character growth stories, and it'll certainly push you to develop other perspectives and think outside the traditional box.
Effloresco Seccundus by romanescue is an unusual Harry Potter/Naruto crossover--it's War AU Hermione as Sakura, with a focus on character analysis and development. There's some really excellent world building throughout the story, but I have to say my favorite part is the character interactions and relationships. The author does a fantastic job of developing characters slowly through believable but difficult evolution--it's a friendship fic with a focus on Team Kakashi, but damn does it have good chemistry. I can't wait for them to grow up a it so I can start seriously shipping.
There's a ton more, but these are just the one's I've been into recently. Please check them out and show your support!
