For those afraid of deletion.
God dammit, this is more inspiring than it should/have/need/has any right to be.
But it’s not wrong, and it’s appropriately meme-y for Tumblr.
The TLDR version is that the relationships you have on here, the friends you’ve made? They aren’t confined to this one place. And, if you have to break away, you can always rebuild.
The people who care about you personally (if your blog is more of a social thing) and/or want to see more of your creations (if your blog is more of a fannish thing) will follow you and still stay in touch with you, regardless if you can be on Tumblr anymore or not.
Tumblr brought us together, but it doesn’t define us.
