- n. Software that attempts to convince the user to fulfil some obligation (such as registration or donation to a charity) by eliciting feelings of guilt.
It's free, with an option for micropayments, so I guess technically it's guiltware.
However, since you can find a great deal of my work online for free here at my webpage, and of course there's the Shadow Unit project, in all its guiltware glory, which is not just me but also Amanda Downum, Sarah Monette, Emma Bull, and Will Shetterly!
Available as guiltware on your Internets, which means that you can read it, and also episode 1 -- Emma Bull's "Breathe" -- absolutely without risk and free of charge, and then decide afterwards if you want to cast us a few paltry pennies dollars for our hard and painstaking work, so that we can afford to keep doing it.
So you're using yet the latest in a series of endless shareware/freeware/guiltware programs, developed by people for free to solve hot-spot issues.
