I like this, not only does it let people find the APIs but having a collection like this encourages others to make APIs and to keep them running.

There's not a lot of incentive to create a service if you feel like no-one will ever know about it. I have had a few thoughts for services that I might have developed if I thought anyone would ever see it.

There's probably an argument for sponsorship here as well, not as a vehicle for advertising, but just companies paying for (or supplying resources) to cover the ongoing costs of the service as a public good. I wish I could make something that worked and could put it somewhere and commit zero mindspace to billing, server maintenance etc. and just have it keep running, forever.
