Red Sweater software has acquired weblog authoring application MarsEdit.

Developed by NewsGator Technologies, MarsEdit provides users with an email-like interface to help them publish their blogs to multiple blog publishing systems.

The software is already widely used within the blogging community. "Nearly every word I write for Daring Fireball is published through MarsEdit," said John Gruber, author of the popular Daring Fireball.

Red Sweater Software founder, Daniel Jalkut, says he is "passionate and confident about steering MarsEdit into the future".

Red Sweater Software will continue to offer existing MarsEdit customers free upgrades for all 1.x releases of the product.
