Some stats:
Dan) Following: 58
People he follows who aren't youtubers/musicians/actors/models (or somewhere along those lines): nasagoddard, sophiehellyer, stationcdrkelly, kaitakesphotos, myspacetom, stephen_, ricothezonbie
Theories:
1) nasagoddard and stationcdrkelly are accounts of space stations/astronauts and they have really sick photos of galaxies, understandable, I'm sure Dan has said something about being fascinated with outerspace before, it fits the persona
2) myspacetom bc he is a shitposting-meme-loving-fuck at heart
3) ricothezonbie is a misspelling of ricothezombie, who, when googled, is Rick Genest, the man who is completely tattooed, a model, and a spectacle in his own right a few years back. fyi his real handle is rickgenestofficial, Danny get with the program
4) i have no idea who stephen_ is, I'm assuming it's a mutual friend of both Dan and Phil as they both follow him, and outside of his first name there's no other identifying info on his page. That being said, a majority of his pictures are geotagged at Dublin, Ireland, assuming he lives there. just had a thought and did some looking 3sixty5days, his first name is Stephen, right? (yes) and he lives in Dublin, right? (also, yes). I think it's an unofficial/unverified account of his for artistic photos, i'm an idiot, NEXT
5) kaitakesphotos???? sophiehellyer??????? aesthetic???? thoughts??????
not specified earlier but still interesting/notable: following all of 1D, kim kardashian, givenchy, ricardo tisci, kanye doesn't have instagram, but we all know dan would hop on that ship asap
Some more stats (really messed up ones):
Phil) Following: 55
People he follows who aren't social personalities in general: sophiehellyer (wowow i didn't notice the first time), kaitakesphotos (how did i miss this one too), mememolly, themersk, lomasca, savagenoodles, eschewal, ashleesuv, tuskalexander, mikestoke, alparrington, robertjamescook, tomcoolio, rachelbache, ffxrules, vixylou86
Older/currently more or less inactive youtubers he follows: xfawnx, lexcanroar, crazycade, maddoxhardcore, tehwebguy
Theories:
1) Because instagram shows the people you follow in reverse chronological order, relatively speaking Phil started following sophiehellyer and kaitakesphotos much more recently than Dan, with the two accounts near the start of the list for Phil, while closer to the middle for Dan. ?????? are they friends? did Dan show Phil some accounts with photography he admired? who knows
2) mememolly works at a media consultancy agency in NYC
themersk is a designer, filmmaker, animator, writer, illustrator, creative person based out of NYC
alparrington (private account wow okay) co-founded a company that allows other companies/talent (mainly media from what i gather) gain followers and activity and general internet buzz. Notable clients include BBC 3, Netflix, Redbull, and Mattel. Compant based out of London.
savagenoodles works in Leadership and Development (often called Talent Development), from Leeds.
ashleesuv works for a creative production agency. London.
tuskalexander works for a digital agency in Northern England. Writes for magazines, newspapers, does other projects, idk.
lomasca is a "social media marketing exec' out of London. (twitter just let me know phil follows him there as well)
Pattern? Secret interest? Friends from the postprodction at York days? What's good, Phillip
3) eschewal is just one photo that he hasn't liked, and a bunch of phandom members commenting on it 'why phil why' personally i think dan's meme persona is rubbing off on him just a touch
4) tehwebguy is the co-founder of Summoner's Con, which if I recall correctly, Cat is the other co-founder of! He also co-founded playlist live (wowie) and sovndwave which is a library of royalty free music for youtubers to use in their videos
5) tomcoolio, just sounds familiar, idk
6) rachelbache works for the New Zealand Herald as writer. Lives in NZ.
7) ffxrules takes a lot of pictures of his abs. None of his photos are liked by Phil.
8) vixylou86 has a blog, assuming she's a friend of phil's, born in 1986.
this boy is so confusing
