LinkFester is a tool to make it easier to put together a daily linkfest for a blog, or email rundown.
Start by bookmarking the pages you want to post using Diigo, Instapaper, or another social bookmarking tool that publishes an RSS feed.
LinkFester will read the specified RSS feed, and return it as a list of HTML links or markdown.
Markdown is a little easier to read and edit than HTML. Some blogs / editors let you post markdown, and it can be translated to HTML by a web app like Daring Fireball's Markdown Web Dingus, or a native editor like Mou for Mac OS X Lion, or Texts.
