This is what the big numbers in Dashboard page URLs are for… I always love the (rare) times when people notice this because it was my baby.
— Tumblr’s Marco Arment on the way the Dashboard prevents newly posted items from disturbing its pagination flow. I have noticed and loved this feature for some time. It’s up there with the way Tumblr rewrites search URLs containing query strings (to remove them), and — as previously noted — the plain text description of how long ago a post was made (eg. “9 minutes ago”).
