Therefore my pitch for SOAP is pretty simple. We want to connect to Web Apps made by other developers. My two examples are the web-based search engine and spell checker. Simple first apps, no-brainers, easily monetized, and areas where user choice is essential. Imagine that a British writer might want to use a different spell-checker from an American writer.
Every site is searchable.
Build a relationship with the most innovative web writers. Only index the content, not the template. And do it in real-time, not based on a crawl. When a page changes it's re-indexed immediately, not some time in the future. Search engines and spell checkers are user-oriented things, therefore should help users understand the value of technology that connects their writing to essential network services.
