Dead Projects
I tend to take it for granted that services becomes cheaper with time (byte-for-byte, at least), and had assumed that whatever dregs of novelty I left lying around could be maintained at a cost that is, relative to other expenses, essentially free.
While some services have gotten cheaper with time, they're not the sort of services I want to buy and have made the services I care about more expensive.
Consequently, the Projects page now has a section for all the things that are no longer hosted anywhere.
