Posterous has themes now. AND thanks to them letting you use CSS and html you can build your own. I like this idea, but what drew me to posterous was it's simplicity and the LACK of themes. I fought wordpress themes for so long that I didn't even feel like writing content because of the pain in the butt wordpress.org had been for me- I didn't even want to log in! So I do like the pretty themes, heck I'm sporting one already, but I hope posterous stays true to their roots and keeps it simple. --side note: theme designers don't advertise their name or links to their work here as they do on the wordpress and tumblr themes.
