Ricky Dillon. Conor Franta, Tyler Oakley, Caspar Lee, Thatcher Joe, MANNNTV. (I'm assume we aren't just listing LGBT youtubers)
I must add more to my list: Tyler Oakley Connor Franta Colleen Ballinger (PsychoSoprano) The Fine Bros Hannah Hart Grace Helbig Markiplier (he's growing on me...) Superwoman Ryan Higa I actually can't believe I forgot to mention MAMRIE HART!!! She is by far the funniest YouTuber out there and I think that she is so underrated. She doesn't even have 1million subs yet which is almost criminal to say the least :/. Seriously, every time I watch her videos I end up in tears from laughing!!!!
Flula Borg. Nothing quite cracks me up as much as him trying to decipher english sayings. https://www.youtube.com/watch?v=qsXyRVQN70U
Maybe The Nostalgia Critic or AVGN. I watch them both. I don't really watch any regular vloggers, though.
the ones that come to my mind at the moment are: TheFineBros (love the React show - it's very clever) vlogbrothers (been a nerdfighter ever since I discovered YouTube. it's my way of studying for some subjects and my way to keep up with John's literature, as he's my favorite author) RoseEllenDix (they're just the cuteste couple ever... everything I aim to have in a relationship) theellenshow (in my country, they're still showing episodes from at least two seasons ago so this is my way to keep up with current "events") clothesencounters (flawless style - always helped me getting out of my comfort zone, fashion-wise) Beckie0 (I think I have a bit of a crush on her... but she's very interesting and she seems to have the same views/tastes as me so, naturally, I adore her videos) Film Festivals and Indie Films (pretty self-explainatory) ItsWayPastMyBedTime (Carrie is my platonic bestie) JacksGap (incredible filming skills, outstanding content and Finn) Mackenzie Johnson (awesome music, always) whatever (never fails to make me laugh)
He was pretty awesome when he was less famous. Nowadays, many of his videos feel like the 15 minute commercials on TV. It feels as if he's making youtube videos for the money and not for the enjoyment out of making them.
Definitely Ashens is my first favorite, second is RhettandLink their Good Mythical Morning show is awesome and I learn a lot from their videos, third is JoxerHD he is small youtuber from the Netherlands. He does exclusively Skyrim let's plays with Argonian characters, and he uploads once per day at the least most of the time. He has an awesome accent and he says tons of hilarious stuff like "monies".
