Awww, this is so heartwarming to read. I never really found that same sense of community and connection on Tumblr, but I really love to hear about other people's experiences. It's wonderful that the platform was such an educational space for you, and brought you into contact with people and perspectives that helped shape your own perspective and priorities.

(Also, hooray for the doctorate — always lovely to meet other people who have or are pursuing PhDs!)
