On February 15, 2008, Jason Kottke put together a list of single serving sites, which are web sites comprised of a single page with a dedicated domain name that do only one thing. (See Sometimes Red, Sometimes Blue for an example.)
Soon after, two quick thinking web programmers took the idea and ran with it.
One created a single serving site that lists other single serving sites.
One created a single serving site that serves other single serving sites.
I smell an infinite loop growing somewhere in this whole mess…
