RocketPost blogging software is the first productivity app for blogging, designed for serious bloggers and business users. Unlike low-end clients which are just helpers for blog servers, RocketPost is a full-blown, standalone editor which puts the writer in control. It’s the only blog editor with WYSIWYG editing, full local editing and full blog import. And it works just like email, so you already know how to use it.

RocketPost reduces the pain of blogging with one-click Technorati / Flickr / Del.icio.us tags, photo editing, instant photo albums, automatic cross-linking to related posts, quote tracking, quick linking, drop caps, pull quotes and a running word count. It works with Blogger, TypePad, Movable Type, WordPress and plain FTP space. And its fully multithreaded design lets you edit multiple posts and publish to multiple blogs at the exact same time, so it never slows you down. RocketPost is the most advanced way to blog.
