And then there's the game hacking software... there's way too many listings related to "game hacking" when they all pretty much do the same thing. Same for the Firefox plugins that let you edit a page, seriously just list Firebug.
Maybe it will be easier if I just list a few that I believe should not be included in the list:
PHP.net
Google Earth
WinDirStat
Morpher
ResizeEnable
Turbo
pic2ascii
distrowatch (All the description says is: "Yeah, Find the distro you want

Lepton's Crack (Out of date, Cain & Abel and JTR are superior)
Visual IRC (Last update July 15, 2007)
Instructables (Doesn't seem to be that useful to someone on HTS)
Also the list should be alphabetized.
