We all love Tumblr for its ease of use and unique social blogging features. But we really love Tumblr because the right theme can turn your humble cat musings into sophisticated works of web literature. Just click that "install" button and, "Look Ma, I'm a web designer!" (Our judges would have also accepted, "Mmm, I loves me some gradients.")
Tumblr's theme garden grows bigger by the day thanks to the contributions of some premier developers. Whether you're looking to pimp your existing blog or arrive on the Tumblr scene in style, we thought it helpful to highlight a few of the themes we find beautiful, compelling and feature-rich.
See below for staff-picked Mashable favorites, and let us know which theme(s) you're using in the comments.
