got told at lunch "you feel like Tumblr Incarnate" and i had to tell them i've been here for 13 years and counting. i was here three years before dashcon happened. i saw the mishapocalypse. i survived the gigapause. i've been here longer than the shoelaces post. i've been here since it was hipsters versus fandom and i played both sides extensively by overdoing the sepia filters on everything and making my own flashing galaxy gif edits for my fandom posts. i'm every tumblr. it's all in me
