Sometimes it’s just not worth the trouble
I’m giving up on importing the old entries back into this one. First of all Tumblr has an api for reading and writing. I used this to read (export) the content to XML. However the write method isn’t as easy. Yes, I could write something, but then getting the Disqus comments converted as well is another task. And really I just don’t think it’s worth the effort. I’m just going to start from scratch, or maybe I’ll manually enter some of the better entries from the past.
