Posterous has unveiled an impressive new version of its blogging service, the completely revamped Post Editor 2.0. Like the original, the upgraded platform is designed for simple content management and multimedia sharing, but it's far more sophisticated and flexible than its E-mail-based predecessor.

Posterous users can now upload and arrange any combination of photos, music, videos and documents in their posts, and the redesigned editor includes a dedicated section to batch-upload any media. Uploaded images can be grouped in galleries, reordered via drag-and-drop, rotated, deleted or interspersed with text. Users can now post at any time via the Web by clicking "Post by Web" on the Manage page.
