Is that Tumblr half full or half empty?
I started to look at tumblelog and Tumblr.
"Tumblelogs are like blogs with less fuss. Tumblr is your friendly and free tool for creating tumblelogs", all in all they do look like less fuss than blog content authoring. See:
Wikipedia Tumblelog
It looks like a nice blend of blogs, media, and links, at least to my eye.
