There are countless youtubers out there I have yet to discover but these are just a sampling of those I enjoy. I have separated them into categories based on the content of their videos. Let me know who you're subscribed to in the comments below!
BEAUTY/FASHION:
Michelle Phan: queen of the beauty/fashion gurus. Taught herself how to apply makeup and started making tutorials for fun. Now owns her own makeup line, em cosmetics (available for order on her website and amazon!) with a store in Times Square. Makes videos once a week that are usually too editorial for daily wear but always beautifully filmed.
Jenn Im aka clothesencounters: my fashion idol. Has killer style and a down-to-earth attitude. You will want her to be your best friend. Films once or twice a week and her editing skills are flawless. Graphics are beautiful and the music is unreal.
Sammi aka beautycrush: curly haired gal from the UK. Very genuine personality and cheerful disposition. Recently lost some weight and looks amaaaazing. Great sense of style that is sophisticated and tastefully promiscuous. Apart from youtube, also runs a blog: beautycrush.co.uk. Owns a Frenchie named Captain Riley and lives with her boyfriend Jason.
EVERYTHING ELSE:
Grace Helbig aka itsGrace (previously known as DailyGrace): makes videos every weekday. Each day is a different category of videos but since launching a new channel (because the company she used to work for apparently owned all the content she ever created and did not tell her clearly in her contract sorry I kind of hate them), they are yet to be 100% determined. Very awkward (on purpose) and sometimes slightly inappropriate, yet extremely smart (although you can't always tell). Definitely an acquired taste but you will grow to love her.
Mamrie Hart aka youdeserveadrink: loves consuming alcohol. Used to work as a bartender and concocts amazing beverages for whomever she believes most deserves a drink that week i.e. George Clooney, Lil Bub etc. Enjoys making puns but they can veer on the side of flippancy. Best friends with Grace Helbig (see above) and Hannah Hart (see below, not related).
Craig Benzine aka wheezywaiter: impossible to describe in a few words. Has many quirks/inside jokes with his viewers, whom he calls beardlovers, that will take some getting used to. The most notable ones are his singing carpet, cloning machine (he has created various clones, including Sexy Clone, Quiet Clone, Corporal Clone) and love for his beard. He is definitely an acquired taste and may not be everyone's cup of tea.
Ryan Higa aka nigahiga: the first youtuber I ever watched. Ever since his "how to be…" series, Ryan's career has catapulted. Once the most subscribed in history (until the title was turned over to Ray William Johnson and then Smosh and now, pewdiepie), he remains an iconic video content maker. I find most of his videos are geared towards a younger audience i.e. middle school, but occasionally, I watch them.
Jenna Mourey aka Jenna Marbles: crazy yet hilarious bombshell. Makes the most random videos that will make you confused and cry with laughter. Loves her two dogs, Marbles and Kermit, very dearly. Used to be an exotic dancer and went viral with her "how to trick people into thinking you're good-looking" video -- it was her getting ready for work.
Natalie Tran aka communitychannel: underappreciated Aussie. Makes videos once a week usually to rant/explain a phenomenon she experiences. She then proceeds to act it out with herself (via special effects, unlike Craig -- see above) with sometimes ridiculous costumes and accents. Is hilarious and you will not regret watching a video of hers.
John and Hank Green aka vlogbrothers: usually very thoughtful content, sometimes silly and occasionally educational. Uploads twice a week. Started vidcon so they're practically gods. Hank sings professionally, sometimes in a band, and runs the DFTBA (Don't Forget To Be Awesome) record label. John writes novels, most notably The Fault in Our Stars, and along with his brother, produces videos on other youtube channels: mentalfloss, crash course (topic include US history, english, biology, and chemistry), scishow and more. Call their viewers Nerdfighters and their internet niche, Nerdfighteria. Their goal: ridding the planet of WorldSuck.
HONORABLE MENTION:
Karen Yeung aka iamkareno: beauty/fashion youtuber with very similar style to Jenn
Claire Marshall aka heyclaire: beauty/fashion youtuber with an edgy and casual style, similar to Jenn
Hannah Hart aka harto: friends with Grace and Mamrie, known for her "my drunk kitchen" episodes once a week that were mentioned in a Jenna Marbles video
Collegehumor: a group of creative minds that create a variety of video content. Sometimes inappropriate and even gross but certain segments are quite funny
