Rain is a new application that I’ve written on the Adobe AIR HTML & JS platform. It allows you to easily post to Twitter and Tumblr from a single application. I would appreciate some feedback on the UI experience and anything I can do to make it easier to use. Anyway, here’s the link to the download. Please note, this is version 1.0 so it’s not a finely polished application. 
EDIT: Forgot to mention this, but you will need Adobe AIR to run this application. AIR is a cross-desktop (Windows and Mac) runtime that allows you to build applications that will look and function the same on all supported operating systems. Download it here.
