Just set up a new WordPress in a 'Tumblr' style. I like Tumblr, but of course prefer the flexibility you have with your own WP install.
I'm aware it needs a few nips & tucks, and there's a really odd bug which seems to omit the date intermittently, but I'm posting about that now.
Anyhow, quite pleased with how it's turned out.
Would be great to know what you think :)
