Drivel is a GNOME client for working with online journals, also known as weblogs or simply blogs. It retains a simple and elegant design while providing many powerful features, including support for LiveJournal, Blogger, MovableType, Advogato, and Atom journals. (Systems based off these are also supported, including WordPress and Drupal.)
gfeed is an RSS feed reader for Linux and Gtk+ 2.0. It is designed to be a simple yet highly customizable reader, not an aggregator, which means it is designed for easy integration into a desktop. Its features include: customizable "feed" files that describe a feed; full support for transparency (native to the app) under X.org 6.8 and higher; and automatic updating of feeds based on an interval defined in the feed file.
wnews downloads and displays RSS news feeds from the Web and displays them in a curses page-based user interface or in parseable line-based output. There is support for HTTP gzip compression and decompression, proxying, key binding, dynamic client, resources configuration, and HTML parsing. It was developed as an efficient and simple RSS news client.
Pftf (Pining for the Fjords) is another take at time keeping and work time accounting. It lets you keep track of how much time you spent working on what, figure out how much work you are or were supposed to do, taking into account holidays, vacation, sick time, etc., and build graphs showing the acquired data.
