I feel like dan doesnt know himself when he started watching phil and it really was 2009, not literally 2007, when phil had 100 subs
We know Dan had a youtube account as early as 2006. By early 2008, Phil had over 5,000 subscribers. Since we don’t know exactly when in 2007 Dan is saying he subscribed, and we don’t have accurate sub counts for 2007 we’ll just say that he had somewhere between those two numbers, yeah?
But even 100 subs in 2007 was a lot more impressive given that there weren’t actually that many people regularly making videos on the website at all. Dan said he was buying Smosh merch when he was sixteen. He was watching Bryony and Nat Tran and Shane Dawson. He was clearly invested in youtube, so yeah. My tl;dr answer is that it’s not unreasonable to me to think Dan started watching Phil in 2007.
