Most likely you a looking for KonqSidebarNews or KDE commit statistics.

Other important (?) stuff:

• a TheDot article on the RSS sidebar
• my not very well maintained blog on www.kdedevelopers.org

BTW: If you are running KDE (or trying to get KDE running) on strange platforms like HP-UX/aCC or IRIX/MipsPro I am interested to share your experience.
