"If you wait long enough, someone will write/build/design what you were thinking about." http://iawiki.net/LazyWeb
How did I get there? Google:RSS+blog+etiquette (such a strange query!) led me to http://www.openp2p.com/pub/a/p2p/2003/01/07/lazyweb.html, which links to http://www.blackbeltjones.com/work/mt/archives/000190.html, which wasn't very useful. Google:lazyweb got me http://www.lazyweb.org, though, which seemed to be the definitive resource, except it's somewhat broken and it looks like a not-quite-popular version of http://www.halfbakery.com. However, it did link to http://iawiki.net/LazyWeb, which is good enough to link to.
