I always describe myself as a "perennial newbie" in this scene. If not for a past relationship, I wouldn't be exposed to anime and manga. There's no way out for me after, though it always felt I have lots to catch up on.
I used to do ani-blogging (with noob-level exposure!) for a group blog for three years before it shut down. Due to this I know a lot of newer titles but have no experience with the classics.
Here's how I'd probably describe my taste:
Slife of Life - mundane, everyday experiences can be more interesting that the best visual effects. It can be as zen as Tanaka-kun or as informative as Shirobako.
Realism - it doesn't have to be that realistic, but it has to be plausible. Hence I normally lean on school SoL or work SoL (how I wish there were more of them!) but I pick up a few sci-fis or shonen "worldbuilding" shows if the premise's well-established.
It could also mean how I love when I can find hidden references or discussions to social issues, up to explicit messages of activism and social justice. It can be as loud as Shimanami Tasogare or even a silly romcom like Sankarea (trust me, it's not just a funny rom-com about zombies)
Raging Teenage Hormones - my aniblogger friends labelled me as such after I survived a drama as heavy as Kimi no Iru Machi. But it could be that I just love reminiscing how it feels to be young. Being a teenager also mean experiencing a lot of feelings and a height of motivations - making friends, achieving a goal, resolving inner conflicts, becoming a new version of yourself and so on. Baby Steps and Apple and Honey might be some of my faves in this aspect.
My list's mostly SoLs, BLs, a sprinkling of seinen, shoujo and sci-fi. As much as I wanna watch dudebro shonen I just can't make myself love them (I'm sorry for my friends who bug me to watch BNHA & ReZero.)
Hope you'd still find my list interesting even if it looks too hipster! By the way, I'm on Twitter most of the time, where you can find me squealing on stuff live.
