I absolutely love fluff.....

Depends on the fandom. For Doctor Who its Ten/Rose Baby!/Kid! Fics, Movie AUs, Crack!fics, and Adventure/ Suspense, and Episode Rewrites.
For Harry Potter, its fics that start where Deathly Hallows ended, and Marauder stories.
For My Little Pony its High School AUs, and Journey!Fics, and an occasional Evil!Fic.
I like Doctor Who/Harry Potter Crossovers, and Team Crafted/MLP Crossovers. (Yes they exist)
I don't really like one-shots, and I really prefer novel length fics. i also prefer to read M-Explicit fics. Not for the sex, but because the plot is actually better in Explicit stories, rather than K+ stories.

It sorta depends. Because I'm almost only on the train when I'm headed to school or headed home, I try not to read smutty fics in public because 1, I can't enjoy them with so many people around me, 2, I'm worried someone's gonna catch me in uniform reading a smutty fic. Plus I'm in a school which most people tend to recognise, so I'm dead if I'm caught doing anything embarrassing. When I'm in a rush and I want a quick fix, I read fics with word counts of under 6000. As long as the fic isn't horrible, anything does it for me the rest of the time.

What fandoms are you in?

Doctor who, Firefly, Chuck, Monk, Pentatonix, Superfruit, Superwoman, Tyler Oakley, Dan & Phil, Harry Potter, Wings of Fire... I can't remember everything. One shots are easier to write, and when I want a mood lift fast I just read a fluffy short thing.

Oh my god! You like Monk too! Sharona or Natalie?

Ohhh that's so hard! I really love them both. I haven't finished the series yet, so I don't know what happens after season five. Don't spoil! But I totally ship Randy and Sharona. I think I prefer Natalie, but Sharona is great. Like, Natalie is nicer to Monk than Sharona was and Sharona was always mocking him. I still love them both though!

I ship randy and sharona too. But I think sharona needed to be tough. otherwise adrian never would have pulled himself together after trudy's death.

Ohh that's true, I never thought of it that way.

Fanfiction is pretty cool and I like it when it's with just fictional characters. But if it's using people in real life or whatever (like people part of a band), I don't really like it. I imagine that if the celebrities were to find that kind of stuff (especially stories with "mature content"), they would feel kinda creeped out and disgusted.

I've actually watched youtubers react to fanfiction about it. The people that I've seen (Superfruit, Tyler Oakley and Markus Butler) have been chill enough with it to "reenact" to a certain extent. Danisnotonfire is particularly chill about it, and he reads them. So not all of the celebrites are freaked out by it.

Watch Pewdiepie fan fiction if you want a laugh

Do you mean angst?

yes please do excuse my spelling

Sorry. Its a bad habit. I'm a beta-reader for tons of different fanworks, and just stories in general.
