Steam Greenlight adds non-gaming category for your consideration

Indie game makers have been lobbing titles over Gabe Newell's fence for a short while, but now his company is inviting everyone else to join in as well. Valve has widened Steam Greenlight's crowdsourced approval process to include non-gaming software, with the community voting the most popular and useful apps onto Steam's virtual shelves. We're thinking of submitting a program ourselves, that calculates the time required for three quantities of a decaying substance to fall to half their value, just so we can see everyone's faces when Half-Life Three appears on the list.
