Dylan Tweney compiled a list of 101 fabulous freebies for the pcworld website. The link above leads to the category view of all freebies that dylan collected. Categories include Tune Up: Utilities and system tools, Lock It Up: Security/antispam tools, system-stabilizing utilities and Share It: File sharing and storage services. All categories include program links and a short description of the program itself. Lots of known tools but also some lesser known ones and also some services are included.
This includes well known services like Wikipedia and lesser known ones like the video sharing service Vimeo. Still it´s a great list and it´s worth taking a look.
