I’ve been diligently posting on tumblr, I feel like I have a fairly clear idea of how to distinguish tumblelogs from blogposts. Hopefully this means the homepage becomes more thoughtful and discussion-like.
Tumblr is hosted at their site. At first I used one of their default templates, but now it’s been converted to somewhat looking like the main site. They are very kind to provide a custom option where users can change the html and the css. I took one of the static pages — in this case the gallery page — and copied in the tumblr specific code. The original css is embedded in the html so I stripped it out and created a new css file called base-tumblr.css which gets called by a tumblr specific styles.css file.
