Saved with the link. Notes from 2007 to 2016 are mostly the page's own words, so this is probably an excerpt.
rawdog is an RSS (and other) feed aggregator, based on Mark Pilgrim's flexible feed parser. It's just an aggregator; it's not a weblog authoring tool, nor is it an NNTP gateway, outliner, mailserver or anything else. raw dog probably only runs on Unix-like systems.
