I love text posts. They are what blogging should be about. When you take the time to write something it tells a great story about you. Readers who pause to read your posts want to get to know more about your story. Tumblr is in my opinion a little heavy on the pix and gifs. Maybe writing about why you like the things you like can make a deeper connection with those who follow you.
