Tumblr finally have their official BlackBerry app available for download and so far it looks really good. The app looks a lot like the iPhone version and includes all the features you would want out of a Tumblr app including video. I personally really enjoy Tumblr for quick posting links and featuring media, and a lot of companies use it for their company blog.
Also, remember to use the QR code method for fast downloading.
