reBlog

A reBlog facilitates the process of filtering and republishing relevant content from many RSS feeds.

reBloggers subscribe to their favorite feeds, preview the content, and select their favorite posts. These posts are automatically published through their favorite blogging software.
reBlogs are useful to individuals who want to maintain a weblog but prefer curating content to writing original posts. They can also enable organizations to tap the contributions of their employees, members, and communities-at-large in order to easily redistribute relevant content.
reBlog 1.3 beta has crazy keyboard interactivity -- never touch the mouse if you dont want to, sped-up feeds and items pages, inline post commenting/tagging, and wordpress plugin compatible with wordpress 1.5.
